Just some personal anecdotes: I've come into the orbit of a local "no phones" meetup group in my city. I discovered it by seeing a black and white printed scan of a hand-drawn flyer on a pole by my apartment. Currently it's just organized by one guy who sends out random Signal pings for stuff to do like a potluck picnic, group trip to some free instructed yoga at a park, craft night at a local bar/bookstore, etc., and usually there's ~4-15 people that show up. I organized a World Postcard Day postcard writing party last week, found a venue that would host for free, donated some of my own dollars to provide free official WPD postcards to attendees, and had 7 people come write postcards with me, I convinced 4 of them to sign up for Postcrossing, it was a great time.

If anybody else is looking for change, try setting something like this up. It has so far been free, easy, relatively low stakes, and I think by virtue of the main focus being "no phones", you get some great people who are all tired of the same algorithmic churn.

I became very good friends with someone who I met at one of the meetups and we've done all kinds of things just the 2 of us and have had some really interesting conversations, which is something I haven't done in a LONG time.
