I see the potential format being something much more like a Rotary Club, which in my mind is a group that meets for a meal, hears a presentation on a topic of common interest, but really serves as more of a meet and greet occasion where people can find each other as potential friends who might be interested in talking to each other and doing things between meetings as well.
Possibly there are other groups that meet regularly that we could productively talk about as examples. There's the obvious example of "churches" but there are all sorts of issues with that model, and I do think that what is doable is more along the lines of a "meetup" group, but more organized and therefore more like a Rotary or Lions or Kiwanis or other more recent examples of those old names that may no longer exist.
