I'm reading Accelerendo at the moment. I'm linked into the dead tree version of the book, but you can do the downloading on the internet thing with it too. It's astonishing how many new (for me) science fiction ideas are in it. Want a novel with self-aware alien 419 scams. You got it.

On a related conversational note. The Author, Stross pops his head up on metafilter now and again, and I vaguely knew him back in the late '80s.
I emailed him recently about him being on Metafilter too, what with us knowing each other 18 years ago, and he was all "Who are you." Man, that hurt. Here's me trying to toady up to a member of the netarati, and he has the temerity to not remember me. Me!
