I see in the title that the history stackexchange site is still in beta.
It went way past its 100 days of beta, why it is still in beta?
As I understand it, there isn't really a 100 day deadline. They do want to see progress by the end of that period though. Apparently we had enough for SE to keep us going. There was a fair bit of discussion on this topic in my question How are we doing?
There certianly has been steady progress since then. Sadly, now that I'm a moderator I'm not supposed to be giving out details of such things, but my answer to What Can We Do To Improve the Site has several updates gathered from public data. You can compare that to our current Area 51 stats and see for yourself.
My personal hope is that we come out of Beta sometime soon. I have no special knowledge backing this up, mind you. However, I like the vector we're on.
