Couldn't agree more. I remember years ago when there were lots of social groups available through which to meet new people, and I too feel our "community" is at risk of dying, because of a lack of interaction other than through screen time. In the past I set up a Meet Up group my self which was moderately successful at the time, and certainly connected a lot of (mainly) men in a regional community, however when I left, the momentum dropped and it melted into a number of Facebook groups, which continue to do OK.
I've since moved to another regional area, and am trying to engage with the local community through Facebook groups. I may not have found my tribe, but at least it's providing me with some connection.
I'd encourage you to try the same, and personally prefer Meetup as a medium than Facebook, or perhaps a blend of the two. Don't have huge expectations that others will participate, or suggest activities or events, however my current area has a regular BBQ, which is helpful, and in the past I did lunch groups, bush walks, tennis nights, barefoot bowls etc etc, which attracted a differing crowd. Steal ideas from other Meet up groups, and try to be as inclusive as possible. In my MeetUp group I reminded people it was for Meet Ups, not Hook ups, but that if romance blossomed, that was also welcome.
Good luck with your endeavours, and remember, you're not the only one who's feeling this, but you're one of the few daring to do something about it. Keep up the good work!
