I agree with this article. I also want to add that the future of social is also the interest graph. The author states that people present themselves differently to three groups: work, family and friends. The key oversight here is that if I post details about my run today on my social sites, neither my family, nor my friends, and absolutely no one from my work cares about it. But I want to talk to someone about it. Where do I go to find those people specifically? All fringe communities are unfortunately forums or poorly designed sites that resemble ning. Many of them lack the deep social features that I want as a user. That's why I think that sites like anybeat are the future of social. Social based on interest, not on personal relationship.
