it's like a forum, but instead of making a new thread, you post an image/link/text in one of the bajillions of "subreddits" which is basically like how here you post walls to brickslayers, nonsense to ch0, paper to paper chase, etc. sites like reddit, digg, or stumbleupon are probably what's most likely killing forums (aside from login glitches). reddit kind of works like the forum for all forums; it has subreddits for almost anything you can imagine, internet points, and plenty of internet idiots to argue with, although you'll never see DAO on there because he didn't grow up with internet.
