What we've done is split off a writer's seminar, which takes place before the con proper.
I tend to think there's a lot of discussion of both writing and reading throughout the convention, however. Not all attendees are writers; not all conversations are going to be about writing.
However, we do really focus on the idea of the *conversation*, and the ethos that everybody in attendance has things to add to it. So I would hesitate to call it "just another fan convention." I think we're a bit more socialized than most.
