I got there about ten minutes late (due to aforementioned long walk), but it seemed to be a 'beginner's guide to Terry Pratchett' sort of do, I guess to try and drawn in newcomers to TP. The most I contributed were a few smart-aleck remarks and managing to recommend the novelisation of Doctor Who: Shada to someone (long story: TP was compared to Douglas Adams, and I recommended the book because it was based on a Douglas Adams script).
"What have you been doing since you stole that antique TARDIS of yours, since you first landed on Skaro? Shouting 'Look at me!!! I'm not fighting a war!', while you battle the Daleks all the way through space and time."
