The site has existed since November 2010 and we graduated from beta in February 2011.
We were strong on all the Area51 metrics when we graduated, which is a good place to start.
July 2012 approximate1 change with respect to January 2012 for a few tracked quantities
- Questions: even

We're getting more hits from Google than from all other tracked source2 which is important as Stack Exchange site don't take off unless they have a good search profile.
We got more than 40 new registered users last month.
Taken on the whole the site appears to be growing slowly but steadily. A lot of our metrics show a spiky aspect with a underling modest, linear growth.
1 Very approximate. I eyeballed them off the analytics data available to moderator.
2 This includes "direct traffic" which is presumably our regular users who come in on bookmarks and the like.
