(Not to mention that the costs of just ballot-stuffing the Hugo nomination process is surprisingly low!)

On the other hand, a lot of the good books we had come up with were either 2009 or 2011. "The Fuller Memorandum" (Charles Stross) is better than two or three of the books on the Hugo List. I can't really recommend the new Iain Banks wholeheartedly, although it did show up on a few best-of-the-year lists. "Thicker than Water" (Mike Carey) is one that Marissa liked better than I did, but it was a solid novel (and certainly better put-together than Cryoburn.)
I think the final collected volume of "Planetary" probably deserves a spot--- it was a satisfying ending to a good series. Fables' "Witches" was sort of meh to me, although Unwritten is good to be on the list. Girl Genius is a fan favorite but I don't think the latest installment is necessarily award-worthy.
Three "Doctor Who" nominations is at least two too many; I was surprised "Supernatural" didn't garner any nominations, but Marissa explained to me that the demographics are all wrong. "Eureka" could have a spot.
