My best explanation for this is that most people who come to Wikimedia are drawn more by the notion of free knowledge than by open collaboration. Over 80 percent of Wikimedia contributors are single men in their teens and 20s — in other words, students. They are immersed in some of the most rigid institutional structures in our society — schools — and they have little experience outside of that. When they organize, they naturally draw on what they know — structure.
Hey, someone who actually seems to understand something about the psychology of Wikimedia contributors! We can't have that, no no no.
Of course, much of the rest of the post is kool-aid induced swillage, but at least there's some germ of intelligence in there that hasn't been stomped out by the Wikijuice. The fact that he sees the solution to the problem created by all these teenaged boys as being "more talk" indicates that he still has his head up his ass. You can't make people equal by simply pretending that they are equal.
