I’ve had FB since 2004 or 2005. I never deleted it. I visit once a week. It is a wasteland for me. The only person who ever posts regularly is my brother.
When I stopped using it regularly I switched to… Nothing. While I do have Mastodon most of my chatting takes place through Signal. I have 2 contacts on WhatsApp. I am awful at keeping in contact but people know how to find me if they need me. I send out birthday emails to close friends.
