If health is a topic you’re interested in, I created a forum that matches your description: https://forum.humanmicrobiome.info/
Hopefully, it won’t be too long before Xenforo forums can federate with Lemmy.
I’ve tried going to back to forums after leaving Reddit, but many of them are filled with the same type of unintelligent people you find on Reddit and other social media.
That said, I’d still stick with forums & lemmy over Reddit.
I think Lemmy was being astroturfed during the recent reddit API controversy and exodus of some redditors to lemmy. Lemmy seems much more normal now, whereas reddit is still manipulated, astroturfed, and botted to hell.

I was just thinking about creating a spreadsheet with people’s contact info, notes, and a picture. I guess an app would be preferable, especially if there were a web/desktop version, and it was compatible with a spreadsheet (can export from/to a spreadsheet).
