I was so sad I couldn't participate this time, but glad to see it again and amazed at all the fantastic entries. Josh, I appreciate you putting these together (as I'm sure everyone does), and would love to see them as often as your time will allow. As you can see, there's always plenty of interest.
One minor suggestion: If you choose to go with a holiday theme, maybe try it once where you do it like a month or so before the holiday occurs. These contests have produced loads of incredibly creative and ready-for-publish quizzes, but for contests like this most recent one where the theme and deadline is the holiday, a contestant would have no hope of seeing their quiz published for at least a year. And regardless of that, as an editor I would have loved to have made EPs on some of these on actual Easter or a day or two before, but out of respect for the contest avoided doing so. I mean, I've EP-ed Chewy's quiz now, but it's not as relevant as it could've been.
Anyway, like I said, I really love that we're still doing these contests, and my comment above is not a criticism just a suggestion specific to "holiday" themes. Keep up the good work.
