I think this is really what it is. I've spent a lot of my time here enamored with the quality of conversation, and when I joined it reminded me of the sort of discussion I used to scroll through on forums when I was a kid.
I hadn't seen it since, and I'd gotten so used to the bullshit that I barely remembered the difference. I'd really just chalked up the civility to the forum in question being several dozen regulars who knew each other too well to be dicks.
We need more content, but it's making me kind of averse to pushing so hard to get the rest over here, lest they just bring the shit behavior with them
