I haven't met her (although I went to a panel she was on), but Susanna Clarke won best novel for Jonathan Strange & Mr. Norrell.
The ceremony set a record as the shortest Hugo ceremony ever, finishing around the one hour and thirty minute mark.
P.S. Saturday's masquerade not only started on time, there were never any real delays, the judges were ready when the halftime show was over, and it finished promptly. I am extremely impressed with the logistics at this Worldcon.
