Software I Use

This series is going to be talking about stuff I use on my computer to get my work done. Sometimes they're not the most popular, and I'm sure others will take issue with them, but I'm not issuing awards or anything, I'm simply saying that I, personally, use them right now. My computer is running Windows XP, so you can assume all the software here will work on it, although I'll try to note if there's some other OSes supported. A lot of this software will be free software, either as in beer and/or as in speech. Some of it won't.
