Well, I wasn’t able to attend, but I did get to follow along online. Unfortunately Ustream cut the live feed during Neil Gaiman’s speech because of copyright infringement; for showing clips of the Doctor’s Wife (Doctor Who). Gaiman won Best Dramatic Presentation.
Best Novel goes to Jo Walton for Among Others (Tor)
Best Novella – Kij Johnson, The Man Who Bridged the Mist
Best Novelette – Charlie Jane Anders, Six Months, Three Days (read at TOR)
Best Short Story – Ken Liu, The Paper Menagerie (read in PDF)
Full report on the winners should be able to be found on the Hugo Awards website.
