Thank God you've noticed. I seem to recall that you brushed off this observation for quite some time.
One thing I've noticed repeatedly in the online communities that have scaled succesfully (in a cultural sense) is that the founders/owners/admins tend to take a very active role, both proactively by being role models and also by stepping in and settings things straight whenever they feel the community is straying too far from their vision. Reddit is a good example of this. Joel's forums at joelonsoftware, which fostered a very tightly knit entrepreneur community, were also heavily influenced by the omnipresence of the site owner.
Unfortunately this is not an elegant technical hack, just simple hard work on the part of administrators.
