Until SLS gives some sort of clue about the "soon to come new features" that will utilize Friends I'll just continue to use Favorites and Notes to keep track of other profiles I'm interested or not interested in. Having seen how well the current features work and how well new features and the app have been released I'm not confident that Friends will be more useful that what I'm doing.
Right now the only thing I know about Friends is that it is a reciprocal arrangement and you can see what has been posted on the other person's Wall.
Favorites and Notes are private - I'm not interested in a Facebook type experience.
