Haha, you are so right about the edgier than thou. I like a real "rebel against everything!" attitude, but I didn't find it there. A lot of these communities don't want something different from their own style and end up getting very snobby ("regulars" and "n00bs" and whatnot). I guess that's how I am too, though, really. I can't stand almost any fantasy/sci-fi writing.
Interestingly, I read (and write) almost exclusively fantasy/sci-fi stories. Anything set in Present Day tends not to hold my interest for long.
For the moment, I'm just trusting in sites like Fictionpress and FFN, as well as my personal site (which I have not fully coded yet. CSS is a pain to organize). This satisfies the "somewhere to post" requirement, but not, unfortunately, the "intelligent discussion" part.
