Trouble is Facebook wasn’t around when my grandparents were, but yep 55 next week.
Facebook is more of an old folks thing now anyway. The kids have bogged off elsewhere to get away from their parents and the uncoolness of Facebook.
I still use FB, mainly to keep my parents and family updated with photos and things rather than use pain in the backside email. Keeps them from ringing to check if I’m alive too if they haven’t heard from me 😀 (or vice versa if I haven’t posted for a while because I’ve stacked it somewhere).
Other thing is ride organisation. Though that’s shifted more towards messaging apps (finally got the majority off SMS!), but that has resulted in rides being more of a clique thing, whereas on Facebook it’s more inclusive. On the other hand FB rides can be a bit random who turns up or may risk a massive group when you weren’t expecting it.
I like Instagram for following interesting stuff going on, and that people can’t put long tedious “sick” videos of head cam footage, less likely to have some vidsplaining techniques or latest diary of a visit to another place everyone’s been to anyway.
