There are a lot of crypto forums in the Internet. But the reality is there is very very little traffic there. If you compare bitcointalk with them then I will say it actually 100:1. Only I have seen cryptotalk has some traffic and activity but others are very less.

OP I really appreciate your efforts of listing all the crypto forums on your site and where there is a rating system. But I think you have put very less information about the forums in your description. it should be little more informative.
