Fred Wilson has a few posts on Building Better Social Graphs that are worth reading:
As software becomes social, the creation of the social graph on each web service becomes a chore. I do not believe that you simply want to port your social graph from Facebook and Twitter into new web services. I believe you want to curate the social graph for each and every web service. And that’s how I try to do it on each new social web service I encounter.
The people I want to follow on Etsy are not the same people I want to follow on Twitter. The people I want to follow on Svpply are not my Facebook friends. I don’t want to share my Foursquare checkins with everyone on Twitter and Facebook.
This thread is worth following.
