She wants to know, for instance, how many of her friends on Twitter live in San Francisco. I'd love to know that, and how many of them use Google Chrome, for instance. - Robert Scoble

look at the list of likes and comments on a thread where Robert tries to give away money. - Geoff Schultz {TF}

sovereignjohn: no, the search engine on Twitter isn't that good. - Robert Scoble

She needs this: http://twitterless.com/ - @LarsenTweet

I'm looking for a Tweetie/tr.im/Delicious/CRM app myself. Perhaps a bit more holistic than this, but do let us know if you find one. - Kawika Holbrook

http://nearbytweets.com/ will identify nearby tweeters - Carrie Krinock

http://twittersheep.com/ is close - Paul E. Ester

also atlas http://atlas.freshlogicstudios.com/ and geofollow http://geofollow.com/ - Carrie Krinock

exactly.. I would love to be able to group friends and followers by their location.. This can do much on getting relevant group conversation.. Tweetdeck has a grouping feature but Twitter certainly can do more... eg. I like to be able search certain keyword within a group just because a word can have multi interpretation depend on where you live and what language you use.. - Pico Seno

Perhaps your friend just found a niche worth filling. I don't know of any good Twitter apps with decent address books. - Kawika Holbrook

nearbytweets is cool!! Thanks Carrie... - Pico Seno

This yahoo pipe can plot your twitter followers on a map: http://pipes.yahoo.com/pipes... but it stops at 100. (this one does your friends: http://pipes.yahoo.com/pipes...) I could probably whip up a quick script that shows them all. - Daniel Sims

Wow! Thanks for all the suggestions. So far the http://pipes.yahoo.com/pipes... is the closest. Thanks! Anyway to make it hide my twitter password though? - Susan Barnes

Here's a good tool to find locals, Twitter Local http://www.twitterlocal.net/ - JCunwired

Yup use http://geofollow.com - Andy A.

@Susan, @Daniel I wrote the pipe and there's a 200 friend version here http://pipes.yahoo.com/mmmeeja.... I did have one that would list all friends but it got deleted because there was too much recursion :-( Haven't figured out a way around the need for a password for a map of followers but the API has changed since then, so I should revisit it. - Andy Murdoch

I'm looking for the same thing. We need this, and some sort of twitter quality index... - Andy A.
