I have attended Dragoncon in the past, but it is not likely I will returning in the near future. Dragoncon is moving its date to Labor Day weekend, which conflicts with the World Science Fiction convention. I have been attending worldcons since 1971, and would never dream of going to another con on worldcon's traditional weekend.
I may come to Atlanta for other events, however, and I do sometimes teach at the Clarion West writer's workshop.
