One-Bit Social Networking Doesn't Work
Giles Bowkett's Never Hate. Only Destroy. (disclosure: contains language your local third graders probably use and your work filter might block as inappropriate) contains a side point which crystallized something I've pondered for several weeks:
The whole point of the Cory Doctorow Problem is that the fundamental assumption with Internet celebrities - that a very smart person will always be interesting - is false.... What irritates me is essentially a search failure; I can seek excellent insight on social software and end up reading pointless trivia about a corporate amusement park filled with plastic birds on plastic trees.
This is my problem with current social networks as well. Your information is either public or it's not. You're either connected to someone or you're not. There's little to no sense of context.
