Even if we are already meta enough, I think a meta subreddit is a great idea. Giving a particular topic a specialized and dedicated location does serve to promote that topic, but it can also serve to remove it from more general locations, especially if that is requested or enforced, which can be a feature. (For example, discussion of stackoverflow is not allowed on stackoverflow; it is relegated to meta where people who don’t want it can ignore it.)
Regarding “Less Wrong council” and StackOverflow...
What about meta.lesswrong.com? :P a LW to talk about LW? Or are we already meta enough…
More than enough. Meta is already more popular than everything else.
