Lies, there are no cool people on reddit, because it is literally the worst place on the Internet.
Edit: Oh yeah there's a question. I'm mostly active here at Something Awful, though the latter is a bit too big for me to keep track of more than a handful of threads. There's plenty of places I go to look at stuff or get stuff - 4chan, the Paradox forums, the Dorf Fort wiki and forums - but only the two I'm really active at anymore, especially since /v/ was overrun with people born in the 1990s.
