Kris has done a number of barcamps and other meetings, so I was confident he could keep these uber-nerds on topic for the whole day. With Kris at the helm of the open-space-style meeting day we had probably the best single day meeting most people in the room can remember. At the end of the day one participant said that she'd never had so much fun working so hard. We ended up with seven vision graphic posters and 56 report outs in one day.
Since then a number of participants have asked me how I did it. So I take a lot of the credit whenever possible... :-) only I could not have done it at all without Kris. Kris kept the whole room moving at the speed of conversation. So if you're looking for someone to take control of your next one-day workshop... you know who to call.
