I think friendfeed has almost all the features i would want, except a user base comparable to twitter. Most of the people in my network tend more towards twitter, so FF hasn't proved that useful for me yet. Otherwise you can aggregate bunch of social network profiles already, and for the ones not supported you can add a custom RSS feed.
