The general reference for this topic is Graduation, site closure, and a clearer outlook on the health of SE sitesGraduation, site closure, and a clearer outlook on the health of SE sites.
With 2 questions per day, this site is firmly in the "in-between" group:
Is your site in between these two categories? You don’t have anything to worry about. Regardless of how small the site might be, you have a home here in the SE network.
The site would need to attract a much larger audience to reach the 10 questions/day threshold. On the other hand, it does not need to do this; it can stay in the present form indefinitely, with the word "beta" increasingly perceived as a misnomer by SE.
