I think there's something to the premise of the article, although it's depressing. It suggests that communities don't grow together. They just gather a new set of people in one place. Then the knowledge that's easy to disseminate, and of interest to all, is distributed pretty quickly. And thereafter there's not much to talk about. New information that's good for the forum is disseminated, but only at the rate it is acquired, which is pretty slow. Are there other directions, other ways to grow? - More specialized forums, different types of contributors and different topics? (The Reddit way.) - Or, maybe the problem is that more structured data is needed to stimulate deeper information exchange. Should there be common resources, like TheFunded's database of investors, or point by point evaluations of programming frameworks? (The Wikipedia way.)
