I was thinking of ways we could promote our site, well here is an idea. We can always give a hangout on air that will be broadcasted in our Google+'s page as well as on our YouTube channel (live). The hangout will be recorded, so after it ends we can share the video. The subject being on how StackExchange works and it's rules, and how Islam.SE works and it's rules. Our Google+ page currently has more than 1000 followers and 1000 +1's/likes.
