So, with mini-conf proposal submission officially closed and talk and tutorial proposal submissions unofficially open for a few more days to get in the stragglers, it's time continue the tradition and start converting submission data into graphs!
Up first, number of proposal submissions by date. As you can see, this year we have an even more pronounced spike at the official closing date (July 20) than in 2007. Interestingly, we show a small hump a week out from submission close, just like Sydney did in 2007. Those reminders must actually work!
Next, a breakdown by day of week and hour of day. For some reason weekday submissions mostly happen in the afternoons, whereas weekend submissions happen in the morning.
I wonder if that means Aussies and kiwis submit on the boss' time, whereas overseas presenters do it in their own time. I haven't get added geographic info to the submission data, but it might make for a revealing graph :-)
