Greg Egan: Permutation City, Diaspora, Incandescence.
Vernor Vinge: True Names, Rainbows End.
Charlie Stross: Accelerando.
Scott Bakker: Prince of Nothing series.
I read Vinge's Rainbows End, and I found the futurism interesting (it seems Google is starting to work on the book scanning stuff), but I couldn't really get into the story.
(edit: fixed typo, thanks)
And happy new year to everyone.
