Well, I don't think we'll make changes anytime soon.
Benevolent dictatorship has worked well so far because people mostly like me and trust me, or at least my wikipedia persona ;-). I'm kind and I listen and I try to make lots of people happy.
But that's a pretty vague foundation to project into the future.
1. What if I do something really obnoxious? Not good.
2. What about controversies in languages that I don't understand? It's hard for me to figure it all out.
3. With a relatively small group, figuring out consensus policies and recognizing that my actions do, in fact, reflect consensus, is not especially problematic. But as we grow, situations will likely arise where it's more difficult to say that.
4. And finally, there is a class of decisions that weighs heavily on me, namely decisions about banning. My pleasant demeanor may not reveal how much I agonize over these, in *both* directions. Some mornings I wake up in a mood to ban everyone. Other mornings I wake up in a mood that says that everyone can be saved. So I have to think and worry a lot about these. Despite the difficulty, though, I like doing it well enough for now. But someday I might be exhausted by it, and might prefer a more broad-based procedure.
