Well, to be honest, I wouldn't mind more mature content. Heck, I'd even provide proof of age to SE in order to be able to access it, even if it was via a $1/month additional fee that I'd have to approve.

I'm not talking like full nudity brothels or anything like that (heck, isn't that what AoC is for anyway), but the gambling etc.. less restraints on chat, it'd be cool.
