I added LibriVox and Project Gutenberg (under the new Books section), and Bad Astronomy, to the Links page. I also added the Essays and Short stories sections to the Books page. I've read a lot more than those which are already on there, but those were the ones I could think of off the top of my head (I'll add the remaining ones as I remember them).
I bought the entire Commander Keen series and also a small indie game called Gumboy Crazy Adventures (which is superbly excellent) from Steam. Online delivery of games (particularly indie games) is wonderful. The corollary, of course, is death to brick-and-mortar software stores!
I've been playing a lot of N lately. I immediately realized it was long, but I had no idea (I'm currently at Episode 59 out of 100). It's wickedly fun, go try it.
