I got into Facebook pretty late (around 2010) and it never grabbed me. I caught up with old friends, but the window into their lives that it provided me with just made them seem annoying. I fiddled with it for a bit and then switched to Google Plus for the brief window between it coming up and Google sucking all of the joy out of it. After that, it was Twitter and then Mastodon around five years back.
As for keeping up with friends and family, it’s mostly email, phone, and the occasional Signal group chat.
