Awesome write up. You faced some interesting challenges… all good learning experiences! Loved the “yeah, it’s easy to cheat… don’t be a jerk!” bit. Looks like people were fairly good about it. As for constraining the next app versions, perhaps limit to entries which make use of the newly available native components in some way. Then add a few secret ingredients which the app must have, iron chef style. This ensures people are actually writing apps specifically for the contest. Also, I think each submission should come with an animated gif demo, which would allow a larger audience to vote more easily. Of course, having them on exponent is still a must for those who want the interactive experience. Maybe votes within exponent are more heavily weighted.
