Checking periodically the Area51 page of the site, I am very happy that most stat are at least in "okay" status. Although the question/day stat is still seems to oscillate around the required minimum (5), it seems it doesn't endanger the site's future (btw, there are betas with much smaller q/d and there was an Embedded Systems SE with bigger stat, despite that it was killed in private beta. Or there is the Magento SE with its around 40 q/d still in beta).
Somewhere I've read, that the SE allows a site to leave the beta, if its visit (or q/d) stat starts to get an exponencial grow. There is no objective measurements, the CMs want to see a curve starting an exponencial growing phase. But, unfortunately I can't find this post any more.
The q/d stat of the site clearly doesn't grow, it is in constant, or in a slowly growing linear phase, it is clearly visible. The other stats seem much better.
Anybody knows or thinks more? 5k+ users have access to the site stats, are there positive / negative tendencies?
