Seems busy here. I'm not sure about quality, seems reasonable, though maybe a bit practical and not enough scholarship.
How long will the site be beta for?
Just for your convenience, here is the stat as of Feb '19
Maybe some advertisements would push this, since other criteria are excellent. We just need to explain why the Q&A format helps learning and practicing Buddhism.
There is also a demonstration of Writing to graduate: Writing.SE clamours for graduation
I guess there aren't enough questions per day to graduate -- see http://area51.stackexchange.com/proposals/45110/buddhism -- there are currently 4 per day, and SE might prefer 10.
The last I read though, many months ago, was that SE no longer has a "graduate or die" policy for beta sites: i.e. a site that doesn't graduate can stay in beta for as long as it remains useful.
