Location based aggregated travel info, down to the street level. I want to be able to instantly know historical facts, reviews, tips, etc. about the building I'm looking at right now. - Jason Goldberg

A user-curated/voted guide to the best expert advice on anything. - Jason Goldberg

dont these all exsit or are possible today, bringing together lots of sites... whats stopping us doing these now. is it just the user interface? - Nigel Walsh

that said, I like your idea.... we should have a news network that starts with positive news! - Nigel Walsh

@Nigel --> it's all doable with stuff that's out there. That's the best part of where the net is right now. It's all online, now we get to build cool services to make sense of it. - Jason Goldberg

Jason, this is an interesting idea. Regarding the "expert advice" thing, I would love to get a good version of product recommendations, but in a "wizard" format. Look at HDTVs, I should be asked questions about size, price, picture quality and maybe one or two other things and it should give me the best fit. - Rob Diana

Other ideas? - Jason Goldberg

Jason: the first two could probably done pretty easily as Mahalo apps. - Christian Anderson

Seems to me mashup apps are going to get huge. The companies that have the most open APIs with deep access to information will win the next round. - Christian Anderson

Further speculation: of the 100, 49 will be localized- or verticalized-search related. Another 49 will be mashups that tie econmerce to existing search tools such that the commerce gets more targeted and powered by one's social graph. - Christian Anderson

I think the people driven social space needs a metric. Something portable that identifies users contributions and influence. Something peer mediated. - Richard Zeidel

Christian, I hope you are right about mashups being huge, that would help me a lot :) However, I am not sold on social ecommerce. Product reviews are good, but the "power of the network" or social graph may not extend well with commerce. The social graph tends to use the idea that several people in your network are experts in something. Commerce does not work quite in the same way. - Rob Diana

Richard, I do not know if peers want to "mediate" as much as knowing how they rank. It is the selfish part of social that drives that. Once you start listing or ranking people, you get the whole a-list and a-list backlash problems. Just look at what is happening with Scoble's list today, http://friendfeed.com/scoblei... - Rob Diana

Point your smartphone or iPhone at a house or building, and get all the background information. (This is potentially scary -- one could get all the background information on the residents or inhabitants of the house or building. This is doable now -- the technology and data are there.) - Sean McBride

One startup idea I wish we had was a unified communication platform. Basically, email, IM, twitter, friendfeed or whatever hook into one big "thing". This could probably start as a web app, and branch into mobile and and thick client apps as well. - Rob Diana

Rob: I'm more hopeful on the ecommerce side. For example, I have several photo geeks in my social graph. I'm thinking about buying a DSLR. They know me and suggested a D90. It's not so hard to imagine someone suggesting where to buy one or even selling me theirs over ff or whatever. - Christian Anderson

I agree with Rob. "a unified communication platform" could make life way easier for me. Streamy comes close but I am struggling with the interface. another startup that could be helpful is one that does location based social networking no matter where you travel...couchsurfing, socialect and localwoot do similar stuff. i wish the three could be combined :-) - Freddie Benjamin

Rob: Here's the disconnect for me. The Social Space is about the individual and the individual's positioning is based on their own packaging, contributions etc. Influence is a key factor - Twitter started with followers, Facebook has friends, LinkedIn has connections. But qualitative data begs the SFW - so fukin what!?! We need a measure to understand people and their place - and i think it must combine both qualitative and quantitative metric and be measured by the community you are contributing to....just my $0.02. - Richard Zeidel

Point your smartphone or iPhone at *anything* and get all the background information. Think about that. Products at stores. Places. People. Documents. Vehicles. Any physical entity. - Sean McBride

Sean: See Ted Video Pattie Maes Sixth Sense...http://bit.ly/LdXlr - Richard Zeidel

@christian -- *could* be done via something like mahalo but i think they are more pure play apps. the first is more of a killer iphone app. I have been traveling so much lately that i want something like this. A service that literally can tell you everything interesting you need to know about the exact place you are at right this minute. The info is already out there online, it just need to be LBS/GPS enabled, and and aggregated from dozens of sources. that would be a killer app. forget the tour book. google maps could be this but they aren't going after the aggregation right. - Jason Goldberg

Nigel: In keeping with your positive news network idea, I'd love to do a series in manner of The Soup... a possibly humorous weekly recap of web culture news (from trending topics and blog top stories to start-up coverage and web series highlights). - Sarah Crisman

@shawn, i love it. - Jason Goldberg

Book Recycling. I'd like to see a method developed that would remove the printing from old books and reprint new text.. - Bill Bittner

Jason -- this idea of yours has occurred to me many times, so naturally I think it's brilliant. :) One of the tricks would be to prioritize the mountains of information associated with any given place. - Sean McBride

Richard -- got it: fantastic link to the work of Pattie Maes and Pranav Mistry at the MIT Media Lab. - Sean McBride

Death Alarm: Follow my online activity via RSS feeds (blog, twitter, facebook etc..) to determine if I am dead!, and if so, activate my afterlife macros. Macros include: sending my letters (e-mails) to family, updating statuses("farewell everyone"), posting blog. Death will be triggered by configurable idle time counter (no status updates for 30 days for instance), followed by e-mail and sms check. optionally, real friend confirmation might be required. Death profiles will be transferred to an Afterlife Memorial Social network, where people can talk about the dead person and post content. - denizoktar

@sean I would love to know the history of my house - I have a picutre from 1926 when it was just a field, yet a year later it was built... who by, who lived here - - Nigel Walsh

how about a feature request so that when you comment @nigel or otherwise it alerts you on Friend Feed! - Nigel Walsh

you know I was thinking earlier - Monday, better Detox, would love to use twitter for global support and tweet what I eat - and everything I tweet, automatically get counted for me and emailed to me every day against a plan.. I rushed back to the PC and someone had done it - almost identical to my thoughts... either Im getting slow or someone has read my mind! - Nigel Walsh

@Rob - Isn't this Digsby or something similar - the only thing that misses is Skype. Im also doing a lot of work with people like Cisco right now and they have some very cool UC stuff out or coming out - linking Presence and various other API's. Im doing this as part of an Enterprise Mashup - but this could easily be consumer based. - Nigel Walsh

Twitting credit card. Choose which kind of activities with your credit card to be twittered in your account.For instance: Visa, please twit everything I eat.(Inspired by Nigel) Whenever I buy a food, it will be twittered. (I am assuming credit cards keep track of each item bought. Do they? Here they don't) - denizoktar

One important start up - web 2.0 for education - there are people in the field but it is not "easy yet". Education is inherently conservative and slow to change - something stupidly simple that would allow/teach/train educators how to use and be successful in web 2.0 would be a great startup. Heck i'd even invest in that one. - Dan Morrill AKA Techwag

Another important start up - portable health care - in that people can have an electronic version of their health care records, everything that they can carry with them. Personally it should be implanted, on a special card, and be very secure, up datable. The fun part would be dealing with people's MRI's, and other imagery/telemetry systems. - Dan Morrill AKA Techwag

A critical piece of the social web is status/rank. All the successful plays have some method of measuring one popularity/authority. - Christian Anderson

A just for fun startup - a true and reliable way to rank internet success, while we have ffholic, twitterholic, compete, quantcast, and other systems, where is the one that ties all this together, is reliable, is accurate, and can not be gamed? - Dan Morrill AKA Techwag

Jason: yep, a location-aware iPhone app from mahalo could do what you want. - Christian Anderson

Dan: isn't that internal conversion tracking tools? Or were you wanting to measure other sites? - Christian Anderson

this probably exsits (someone let me know if it does) but when I comment on blogs I want it to update FF automatically - eg Disquss... - Nigel Walsh

Ok. try this one on for size. I'm gonna create a website where every feature, including the first thing we build, is decided by a weekly vote of our users. - Jason Goldberg

I'd like to see a location based social network built around graveyards. You'd create a profile and reserve a physical plot of land and be buried there when you die. Your tombstone would display random status updates you posted to the web throughout your life. And you could look up your dead friends graves on google earth. I've thought about this! - Jon Gosier

give me a chip no bigger than a credit card which recharges my blackberry in 10 minutes - Jason Goldberg

an online incubator that turned an idea(s) into a working site in days not weeks or months.. - Nigel Walsh

Days? Let's throw something together, halfassed, let it go down all the time while we get it working over many years. Days would be great, but if you want something good, you can't throw it together in days. - Dean Clark

Company that makes an iPhone app for SocialMedian - Jeff (the メガマクダジ of FF) from BuddyFeed

I'd like to see a mashup that would work for open networks like twitter, digg, friendfeed etc. that would allow community walls. a block would trigger a whole community to block the same person till a person within the community unblocked. open networks are dying because people don't want to comment on threads with people that they know they don't like. it could be voluntary. we would call these "Unions" and you would have to agree to be a part of one and you could always leave. - Noah David Simon

Some great ideas here. Really like the unified communications idea. - Gavin

How about a startup that encourages hobbies for school aged children - Anthony Farrior

or a startup/networks for artists and animation. Perhaps something that has online tools and copyright ownership. For an extra fee provide help with networking and distribution. - Anthony Farrior

or a start up like peek that provide gps and text communication between parents and kids - Anthony Farrior

or a start up for upcoming clothing designers(not tee shirt stuff) where,again, for an extra fee, networking and real store distribution is provided. - Anthony Farrior

last one, someone PLEASE make me a mobile video phone...As in "Hi yes, i can hear you and see you." - Anthony Farrior

A free 'app' that helps re-educate those displaced by the Internet / automation / tech revolution. - Charlie Anzman

Jason, this would be a great idea for a room here. You could create an identical one on socialmedian and import the RSS feed from it over here. If I have one criticism about friendfeed, it’s that so much of what is shared here, winds up in the rear view mirror, and is quickly forgotten. - Michael Fidler

I can see why you would like a location based service like the one you described. There’s something like it on the iPhone, but I tried to find the name of it on Google with no luck. Additionally a lot of information just became public which would help with such an app. I would like something along the lines of what Rob mentioned, "A unified communication platform". I have a few more ideas but I need to find some info. first. - Michael Fidler

Jason, there’s a site like the one you mentioned about user decided features also. Loic used it to decide what features to add to Twhirl. It’s called Uservoice http://bit.ly/ykT5 - Michael Fidler

We've already started a series of hyperlocal "best of Twitter" city sites like http://BreakingLANews.com. It's a grass roots initiative that provides these city templates free to community hubs and groups in each city, down to towns like Chico, CA http://ChicoBreakingNews.com. It's a unique way to propagate a new hyperlocal marketing model that, unlike sites like Topix, directly involves members of the community. - Pat Kitano

Expanding on the UC idea, I was thinking someone could write a connector for twitter that in essence links twitter to all other chat clients, ie if you tweet msn:ndwalsh then you chat with me.. Same for skype:nigelwals, icq: etc etc... The ultimate comms platform - Nigel Walsh

click sharing company - Thomas Power

An easy way to discover new websites, not content, but great websites. Check out http://www.lynki.com - Aloke Fernandes

@michaelfidler: yes, we use uservoice at XING. It's a great tool! What I'm talking about is using a tool like uservoice in a whole new way, to decide everything from the first line of code onwards. - Jason Goldberg

Hmm I work on a location based iPhone app and unfortunately the GPS is too often not accurate enough to pinpoint the building you're in but can usually narrow you down to a 100 meter area. Also we need a magnetometer on the iPhone to do any accurate pointing (but it's coming in june they say...) - Raj Advani

Raj, the other option would be to provide users a 3D map of nearby buildings so that they could use their human intelligence to find their correct location. But that might be hard to implement in an iPhone app. ;-) - Bruce Lewis

Nigel Walsh, Backtype will import all your comments on blogs to FF. FF is even smart about not duplicating your Disqus items here. - Bruce Lewis

Rob Diana: your TV-Example is exactly what http://hunch.com is all about. - Richard Metzler

Haha Bruce I was going to say wait a minute... - Raj Advani

I like Thomas Hawk's idea of starting a company to comb through old game shows and then selling the DVDs at outrageous markups to the original contestants or their family. http://thomashawk.com/2005... - Davis Freeberg

"Location based aggregated travel info" => Nokia Maps & Lonely Planet: http://www.youtube.com/watch... - Thomas Amberg

One of my weird ideas: Create a User Profile Management Site that allows users to create / update a common "User profile" (could have multiple "personality" profiles - work, personal, family, etc). The profile site updates would push out to a gazillion other sites and update user profile settings with each update. API adoption by a number of other apps is a must, obviously. The idea here is that the user can manage / update all their profiles on a number of others sites via 1 login, set of "settings" in a simple profile, rather than having to go login to a gazillion sites just to update their email address, phone number, etc. Could use Gravatar, that's a similar concept, but only handles Avatars. I want the whole enchilada - all the customary user demographic fields, plus customizable ones for various services, etc. - Susan Beebe

Distributed Indexing (Search Engine, Classifieds, Auctions, Real Estate) Like MLS for web directories / search engines. - Matt Robson

@Susan I've been thinking of something like that for a while. - Gavin

@Susan, @Gavin something like chi.mp maybe? - Dragos Ilinca

Do we really need another 100 startups? I'd rather see one or two excellent startups come through and form their place on the web then seeing 100 coming through and all burning. Some of the ideas listed are pretty interesting and it would be cool if some of them were implemented although I'd like to see a few of the ideas merged together to see a more feature rich and useful service for users. - Nicholas James

I'd really appreciate some feed back on the idea I stated above. I think it addresses a very serious issue in making "open" networks acceptable to the mainstream. I'd really like to hear from some tech people if it is feasible: making open networks acceptable for more people http://ff.im/3i7y9 - Noah David Simon

Coin-based economy for kids to help them skirt the issue entirely of having to ask parents for their credit card to play online games. Coins are kid money (and their parents nuisance money). Let's get coin value translated to online money and watch the revenue pour in. - scott epstein

I want an app that will accurately predict the closing price of the Dow for any given day in the future. I know it’s not realistic, just call me a dreamer. - Michael Fidler

Jason, I was thinking about your idea today, and that would be an interesting experiment. You could call it Tabula rasa. It’s definitely worth trying. - Michael Fidler

I had this startup-idea: http://prezi.com/20331/view/ but I droped it. Now I have another one: 1. Start a communities for science & business topics, 2. provide Conference-Life-Streams with Twitter-Comments as usp like this: http://www.ustream.tv/channel..., 3. Provide further information like news, topic-monitoring (twitter), publications-research, 4. Track the use of that information by the group with a meme tracker, 5. the meme-tracker will built a info-portal for external readers. In this way you get highly valuable special interest sites, which are created by the social use of information. Well, will built a presentation for that... - www.louis-e.de

oh, it's a bit similar to social median, I see ;-) Didn't know that before, sorry. But I can't find info-portals with meme-tracking-technique there. And no conference-streaming. So will built your competitor, haha... - www.louis-e.de

Just in case people really liked the "unified communications platform" idea, I believe it is now called Wave, from Google (http://wave.google.com/). - Rob Diana

Nother idea for startup: when riding public transport, service sends notification when friends are on the same train/bus etc. - André Gallinat

You were right on the money, Rob. Nice Job! - Michael Fidler

A Google Wave app that integrates with Google Health to provide real-time healthcare between Payers and Providers - Jesse Stay
