>Mid-2021, I stop using FB for anything beyond Marketplace.
The only things I find FB useful for are Marketplace and Messenger. Marketplace is an OK way to sell your junk locally (it basically took over from Craigslist because CL was taken over by scammers and CL never bothered to do anything about it), and Messenger is a convenient glorified phone book and chat app which has a video chat feature that actually works quite well through any browser and doesn't require a local client application like Zoom. It's also really convenient that it works through both my phone and through a browser on my PC, so it's easy to switch back and forth (much easier to type messages on a PC, for instance).
