Book Time: Postsingular by Rudy Rucker

I also recently finished Postsingular by Rudy Rucker (you can read the entirety free online at http://www.rudyrucker.com/postsingular/). I'm not usually a huge Rucker fan, but a book that starts with the Earth being almost completely turned into a giant computer that is simulating earth by rogue nanotechnology has me at "Hello". As in much science fiction, the emotional lives of some of the characters makes them seem as if they're strangely unfamiliar with normal emotional lives, but, hey, read it for the fun of the ideas.
