Iminta has a cool thing going for it: you can put your followers in groups and specify which group sees what... I really like the idea of variable resolution for social feeds. Still in beta as of 3/16/08
Socialthing! is in private beta - see everything that's going on with your friends in all the sites you use, easily figure out where you're missing connections with your friends, interact with multiple sites at once, and more!
It’s the same with SXSWi, but the lure of connection, learning and good times at conferences is like the search for magical Disney moments, right? Aww, put on your Mouse ears and go with me on this one….
