Our experience was similar - I'm no Dragonlance fan but I felt so sorry for Margaret Weiss sitting alone there, I went up and told her the new art on her books was nice (she agreed). Todd Lockwood was sitting alone also in the artist's area, we had a chat with him about art and got his contact details so Upper_Krust can maybe get a license for some of his art for the Immortals Handbook he's working on.
Friday was pretty grim, the trade hall was nearly empty. I tried to find out about DOGs games at the 3rd floor and was told there weren't any. Not even a dedicated notice board. Ann Dupuis led the 'Secrets of Great Gamemastering' talk - pity she'd only GM'd FUDGE and an occasional D&D rules-cyclopedia game for her husband... She said D&D rules-cyclopedia was clearly the greatest game ever (except for FUDGE).

I looked through the Buffy books at the Eden Studios stall and was so impressed I ended up buying two of them (for about £45) over the course of the weekend. We chatted with various traders.
We were at the Ars Magica seminar on Saturday, mostly to see Tweet of course. Knowing nothing about Ars Magica, I was the one who asked the panel about how they integrated Christian medieval Europe with the Orders of wizards. There were what, maybe 20 people there? And that was one of the better attended talks. It seemed incredible that they'd get Jonathan Tweet over and not have him say _anything_ about D&D or d20, other than a few scraps gleaned in the Ars Magica seminar (sounds like a great game, but I doubt it's my cup of tea). This seemed to be a recurring theme - a Gencon convention with nothing about D&D!
Sunday was better - we attended the 2pm talk about publishing in the games industry. Ann Dupuis seems a very nice person, but FUDGE is clearly a minority taste. John Nephew is entertaining also, but again not doing anything that's of great interest to me. However they dragged George Vassilikos of Eden, clearly a star, & Ian Sturrock (I think it was) of Mongoose out of the audience, and they had some interesting things to say (about d20 in Ian's case!) before we had to rush off at 3pm to run the EN World D&D game I'd arranged - the only actual gaming we got done the whole time, what with there being no DOGs setup at all.
Later on Sunday, we returned to the 3rd floor to watch 'The Gamers' movie at 8pm, and were lucky to catch the end of George Vassilikos' 6pm talk - as it happens he was talking about the whole industry, and there was quite a lively discussion on whether d20 was going to be the Windows of RPGing - George said he used a Mac. 'The Gamers' was a lot of fun, and at least we went home happy that day.
