Not sure about Lemmy, but I have noticed an influx in loops.video content recently, especially in my native language. That’s probably because Loops is starting to be usable now. There’s some YouTubers I already followed and even some local progressive politicians. This year a project named “digital day of independence” started, that educates people every month about how to switch from big tech, which probably also has something to do with it.
Same. Plenty of free hobbies exist though. Hiking, learning a language, identifying plants (check your local weather service if you can contribute your findings), geocaching, streetcomplete, attending a communal board game night or gardening group. Libraries hold all kind of events for all walks of life.
Some sort of political engagement can also be fun and additionally help find friends. There’s cryptoparty to teach about privacy. Some environmental groups host day trips with volunteers to clear or repopulate strips of land. You can ask your library if you can offer a workshop of some skill you possess.
There is honestly so much free stuff that I didn’t know about yet a couple of years ago.
