I used to go through the chans sometimes, but then I got bored of it. It's usually just a bunch of people trying their hardest to be an asshole by stealing things others said long before them. Nerds should never be given the power of anonymity, because they all pretend to be hardcore and put up lots of image macros.
I do think a lot of stuff to come out of it is funny, though. Free porn doesn't hurt either.
