I’m not sure.
Despite participating in the event this year, I didn’t have time to pay attention to what other people were posting. What I’d like to do, now that the event is winding down, is go back and read other people’s posts to see who actually did participate. I’ll add the best posts I find to the corresponding post for a given topic, and once I’m done reviewing things, I’ll have a better idea of how to answer this question.
That said, I could be fun to do this with Lair of Secrets. I could see David Moore and I tag teaming the posts topics; it could be interesting to compare and contrast our takes on a particular question or topic. Running them as a series of quick-hit videos on the website and on Twitch could be fun (though also a decent amount of work).
