I watched an excellent podcast last night about the state of the hobby (warning, it is 31 minutes long)

While the focus of this video is modern, I do think they are some takeaways for vintage as well. I found the video and the comments section interesting.
My take on it is that it will be interesting to see how the hobby strives post the last 3 years. An issue have seen recently is a "disinterested" collector. Some friends who have been in the hobby a while and some who have recently joined are taking a pause on buying and collecting. Could be a variety of reasons, but it is not like it was a few years ago. Maybe this will pick back up next year.
