Thank you, and yes I'm definitely interested.
Cool! I'm a bit of a science fiction fan, so this is a fun, eclectic list.
Metaplanetary by Tony Daniel is a great place to read more. An enjoyable read with some deep thought. Characters are a little shallow would be my major complaint.
Altered Carbon by Richard K. Morgan plays with the possibilities of recording and recreating yourself.
Steel Beach by John Varley deals with a future without Earth - and the fact that we lost Earth to alien invaders is entirely incidental. If that doesn't intrigue you, it deals with immortality and the dangers of complacency, in regards to one very strange journalist, a computer heading off the deep end, and a lot of crazy people. Quite fun.
The Diamond Age: A Young Ladies Illustrated Primer by Neil Stephenson - I'm not sure this counts as strictly transhumanist. I'm pretty sure it counts as strictly awesome, and explores a whole lot of territory.
Also, if you happen to enjoy webcomics, I recommend
Dresden Codak. It's a slightly less serious look, but anywhere that comes up with 'The Future Preenactment Society' and "Pretend to be a Time Traveler" day can't be bad.
It really doesn't help Vinge, IMHO, that he's a weak writer, and frankly the singularity scares the crap out of me. I don't really think there's a hope that something like that would be anything resembling benevolent - its motivations would be beyond inscrutable after a short time.
