Alina and Jake point out the COLT Call for Open Questions due May 11. In general, this is cool, and worth doing if you can come up with a crisp question. In my case, I particularly enjoyed crafting an open question with precisely a form such that a critic targeting my papers would be forced to confront their fallacy or make a case for the reward. But less esoterically, this is a way to get the attention of some very smart people focused on a problem that really matters, which is the real value.
