I am OLD - I had FB when it was a private, university-only, and people were giving out their dorm buildings and rooms. My FB was becoming a ghost town 5 years ago, so I stopped using it, then deleted my "real" profile. I maintain a shell account now for Marketplace, Groups, and Messenger. I have the "light" apps on my phone with all requested permissions denied. Marketplace SUCKS from a usability perspective, but it's become equally as active than CL in my area. Groups are a goldmine of information - my neighborhood has one that is active, I have an active one for my model vehicle, and there are B/S/T groups that are nice, as well. Groups have effectively killed the old Forums/Bulletin Boards. Messenger is required if you want to buy/sell, etc. I don't use it for anything useful.
