Except now it's all on Facebook and it's incredibly hard to leave Facebook, because all communications with any type of group happens on Facebook. I have friends who can't leave Facebook, because their kids soccer team holds them hostage. Leave Facebook and we'll kill your child's social life. I can't even join the parents group for my child's school, almost no one else will do it, because it takes time, so they are lacking parents, but it is coordinated on Facebook.
I used to organise playtime for toddlers once a week, no one else wanted to do, but the kids loved it. Everyone was used to everything being organised via Facebook, where I don't have an account. So the communication was done by someone else in the umbrella organisation for all local sports, gymnastics, e-sport etc. More than once I showed up to get everything ready only to learn that the space was booked for something else that day, being cleaned or renovated. Everyone else had been informed, expect me, the guy who was suppose to be in charge of the damn thing, because the organisation had no real website or mailing list to speak of and just expected everyone to be on Facebook.
Everything is on f-ing Facebook, Sports, clubs, hobbies, reselling, announcements of everything local, and only on Facebook. The only exception is professional meetups, which Linkedin will happily inform you about two weeks after the meetup, stupid, brain dead, algorithmically power "news" feed.
I want mailing-lists and Usenet, but everyone else want a mobile app and apparently Facebook.
