It's interesting to imagine what a market solution would do to this.

On the one hand, the vibe is very much "show up and let's talk like friendly socialized people" and I bet that's a huge amount of the joy in it.

On the other hand, perhaps the people who _really_ want to talk to Matt should be able to? And while imperfect, paying for is an unshakeable signal that you _really_ want to.

(Note: I started this comment eight hours ago and apparently didn't submit it, so maybe someone has said the same thing in the meantime. I'm too annoyed with myself to check.)
