Hey, that's been on my list for a while, but this was the first time that three important factors were in a Barnes & Noble at the same time:

1) A copy of Snow Crash
2) Me
3) Money for buying books for me

But, as I said, I expect I'll be reading more of his stuff. It's so nice to be reading a book that exposes me to new ideas and concepts, and actually makes me think about them. So many books at the bookstore are ones that I have already read, just with different character names and a different author. I'm getting to be a bit of a hard sell in the sci-fi / fantasy section.
