The 2008 Hugo nominations are out. You can vote. Just join the current Worldcon as a supporting member. (Google worldcon.)
None of the novels I liked made the ballot, but I do have a few recommendations if you plan to vote.
Best Novella, "Memorare" by Gene Wolfe -- not only a great story, but Gene Wolfe has never won a Hugo and it's about time.
Best Dramatic Presentation, Long Form. For some reason, they put the entire first season of Heroes as one long drama, while all the other tv shows are in "short form". That means I have to choose between The Golden Compass and Heroes, which sucks.
Best Dramatic Presentation, Short Form. The first web cast to be nominated for a Hugo is Star Trek: The New Voyages, "World Enough and Time".
Best Professional Artist: Phil Foglio gets my vote.
Best fanzine: Challenger.
Deadline for voting is July 1.
