Derek, for one, I like the online version of the event catalog better than an actual book. Personally, I wouldn't mind seeing the program book and coupon book combined into one, and trimmed down to include only maps, important info, people, advertisements, and coupons. It is time for Gen Con to move up to modern technology and develop an official iOS/Android/Win phone app for events. The unofficial app does a great job, perhaps contacting the individual who makes it and see if you can't work together with him.
The app needs to have events that are searchable by event ID, title, game type, etc. Same as the online catalog. Events should have a link to the appropriate location map linked as well. Also, the dealer hall needs to be searchable by vendor name and location where the booth can be highlighted on the map. It's nice to be able to see a number, but a highlight on the map would be nice. These are just a few of my thoughts on making Gen Con navigation a bit better. It would be easier for the attendee to be able to find an event online using their phone/tablet/etc, then pull up a map in the book without having to flip back and forth between pages.
Either way, I liked the program book.
