I want a good community. And by "good" I mean smart, insightful; full of people who make me stop and say "holy fuck, this is brilliant". I don't mind if it's slightly rough or slightly unwelcoming, as long as users are rational enough.
I also want a diversified amount of topics to talk about. Cooking, gardening, games, anime/manga, so goes on. Once in a blue moon I do talk about politics and society, but I'd rather talk about something else, you know?
