No it is rather node like. Not really found in one specific area. We are talking close to 200 Million users. So they employ the TwicketTwicket for bugs, support and feature requests. Turn around time can be from a day to a week.
You can say the moderators (or tags) of *meta* are
- API notice :@twitterapi
- Trust and Safety Lead :@delbius
- Safety :@safety
- Feedback :@feedback
- Twitter Mobile:@twittermobile
- CEO: @ev (They rarely respond to the normals ... only verfied)
- Support: @support
- Unofficial Support: @TweetSmarter
So this is where information flows. Anything else that happens on *meta* (e.g showing interesting stats, discussing proper etiquette, how to do stuff) is discussed on many blogs.
