I bounce around a few times a day between the news sites (CNN & Fox News mostly, then I try to figure out the real truth somewhere in between the propaganda on each). Then there's Facebook (mostly for work). Then depending on what the day's project is, it's a slew of programming sites to help me figure out why something I'm doing isn't working right or to help me debug and fix something that someone else wrote.
Truth be told, I'm online so much for work that I don't really enjoy doing much else on the web when I'm not working. I try to disconnect from it as much as possible, but always have my iPhone there in case something comes up.
