If you want a model for similar things, social clubs were very popular from the 50s up until the 80s and 90s. Rotary, elks, etc. I suspect when millenials star

If you want a model for similar things, social clubs were very popular from the 50s up until the 80s and 90s. Rotary, elks, etc. I suspect when millenials start to age they will come back, minus the culty parts. There’s also expat and reiree communities where such things occur. College towns frequently will have public meetings or lectures.
