50/50 with Friendfeed and Google Reader. I have been a heavy GReader user for months, and Friendfeed has dovetailed nicely into that usage. People are friendlier and more interesting on Friendfeed than other social media sites. - Mark Trapp

I'm a heavy Google Reader user, FF and twitter. Those three are my most used at the moment - Liz Polay-Wettengel

Same as the previous three comments, although lately my activity on Twitter isn't as flowing due to reading up on blogs I find through FF/GR! - Joe Dawson

Twitter, FriendFeed and I just opened a StumbleUpon account last night. Pretty cool. - Sharon McPherson

latest, i like very much friendfeed - Laurentiu

FF, Twitter, Pownce, Digg and instant message. - MikeonTV

Twitter has my friends, Google Reader has my feeds and notes about particular posts. Delicious is for my bookmarks. FriendFeed rounds them all together.. - MLx

FriendFeed the most, use Mento for one-stop shopping on my bookmarking and have started using Greader as well. Oh and I still use Twitter some - Marco(aureliusmaximus)

Google Reader 40%, FriendFeed 40%, Twitter 10%, Others 10% - Mike Reynolds

facebook. b/c my friends are there. twitter b/c it's easy. FF b/c it ovides a wider view. Dinner with friends b/c i like food and talking to folks - @baratunde from twhirl

Pownce is my most active. I check it every day at lunch and in the evenings. I've made some great friends there, many of whom are into Web development and social media and others who aren't. It's a very friendly place and the nature of it makes it great for having long conversations as well as for posting links and files. I also check socialthing once a day to get a good overview of my friends activities on Pownce, Facebook, Flickr and Twitter and am now popping in here more often. - Heidi Cool

I seem to be more active on Twitter and Digg. I need to try Pownce. Never used it - Ritu

Digg, Twitter, Friendfeed...not sure if GReader counts as SM the way I use it. - John Wesley

I digg everyday, but I am beginning to enjoy stumbleupon more and more. There is a better feeling of community on SU than on digg. I am fairly new to Twitter, but I am becoming addicted to it. It will be even better when I get more followers(hint,hint) - Shane Floyd

does ff count it's the only one i go to now - Anthony Farrior

I haven't really been active on FF. I recently started using it after this room was created. This was a wonderful opportunity to pass to connect with you guys. Glad I tried FF. I need to give Pownce a shot though. hear a lot about it - Ritu

Digg, Facebook, Twitter, FF most often at the moment - Kimberly J
