What we’re really trying to figure out are the right tradeoffs. And there’s no question that there will be tradeoffs. The question is whether, in the end, Facebook is creating more value than they capture. I’m finding Facebook increasingly useful. And I think a lot of other people are too
This is a valid point, I guess I just am not getting much of nay value from Facebook these days. I highly recommend reading this entire post, it is the best summation to date that I have read. I would also add that there is a trust factor with these types of networks, and Facebook is slowing losing that. Trust once lost is almost impossible to regain on the web.
