Ok, there's only one day, but it feels like a multi-day event.
First, I was surprised to find that there were several people who traveled great distances. Kudos to everyone who made it out. I'm sure it was worth your while.
As a presenter, I was sorry that I only got to attend two of the other presentations, neither of them by my ex-teammates, who were presenting at the same time. Each presenter gave his talk twice during the four sessions (14 presenters total, I think). Even the full-time attendees still then had to choose between presentations.
My talk (powerpoint here, one-page summary here ) went well, I thought. The two sessions had different feels to them. I incorporated some of the questions from the first session into the second, and as a result of that and other changes, I ran over on the second session after having 10-15 minutes in the first one just for questions. The second session went smoother as well, as I didn't have to fight over as many words, and knew when to just go ahead and leave one slide and start on the next.
I left before the panel discussion, as it was already after 5 pm and there was still a presentation going on in the auditorium.
Good job by George and Tiina assembling the myriad volunteers and vendors. You never would have known that this was the first of its kind by how well things seemed to go. Thanks to them.
