Good advice? I've been around these sites for a while... I don't recall much that is considered good advice. Opinionated, sure. Defacto ways of having a successful site, nope. If that was the case, you'd see hundreds of new sites popping up daily.
The fact is, forums are a dying breed. *tracy perry enters - blah blah blah the search function of facebook and twitter sucks, can't have good discussion blah blah blah* Instant answers, exchanges, discussion is where it is at. Simple as that. Find an Admin site on Facebook, Twitter, YouTube and Instagram practices, and what increases your followers to have better monetization, that's the ticket.
