I just wanted to point out also Shelfari - Welcome to Shelfari! Read, Share, Explore!.

Its like a social site for readers. It's got a real nice tagging and review system. So damn nice for finding new stuff.

If you want recomendations, read my page on there, but before any thing else, I recomend Neuromancer by William Gibson, Crime and Punishment by Dostoyevsky, and Gravity's Rainbow by Thomas Pynchon. Pynchon can be a tricky read, but its worth it.
