I'm not certain of that. In every focused forum I've frequented, when a sense of community grows, the focus turns inward instead of staying on the stated subject. I think, for instance, that the chans' insistence on anonymous posting and ephemeral content helps keep most of their boards full of posts focused on the board's topic, rather than the poster's reputation.
