I have a Google homepage with thirty or so RSS feeds on different topics. So I read the news a lot. Mostly I download music and ebooks. If I'm not reading a material book then I'm probably looking up articles about science, math, programming, government, economics, etc.
IRC is boring. Forums without forced anonymity (including Facebook and the like) are downright stupid. Besides 4-ch I don't really socialize online, except for on Omegle. It's a vice of mine to troll, surprise, offend and confuse people on a medium where a simple 'Disconnect' is all it takes to talk privately with another unknown user.
