John at SF Signal lists some of the books he liked best in the past year, and also provides a big round-up of his story-a-day project for 2006.

Green Man Review has best-of-the-year lists from literally dozens of people, starting with Neal Asher and Kage Baker.

Update, 1/3: You don't look so bad -- here, have some more.

Rob B. has posted a Best-of-2006 list (and an addendum) -- among the books he mentions are Crystal Rain by Tobias Buckell; Joe Hill's amazing debut collection 20th Century Ghosts; SFBC's fantasy Book of the Year The Lies of Locke Lamora by Scott Lynch; and David Louis Edelman's Infoquake.

Oh, and I did it too, over on my personal blog. (Many of my choices, I should warn you, aren't SFF at all, and a few are even those trashy "comics" stuff.)

Update, 1/8:

Possibly the last of these lists -- Jeff VanderMeer, at Locus Online, offers a selection of twelve titles he thought were overlooked in 2006.
