Re:Well... real-life social networks aren't open (Score 1)

I whole-heartedly agree, too. It is exactly the closed (albeit weakly) nature of online social networks like Facebook that make the users comfortable. On second thought, however, I do find it interesting that people I barely know ask to be my friend. Then, when I say "yes" I have to watch the boring details of their lives roll by on a newsfeed. Hmmm. Do I really need to know that Micah and Joel are now friends? But yes, I think that the closed nature of any social group adds value to that group.
