Downsides of facebook:
People tell flat out lies on it, and those lies get passed around and take on a life of their own.
There are always these flattering comments, always from men with two first names, and they are always retired military or doctors and they are always widowed, and they want you to send them a friend request. (Yeah, buddy, not born yesterday).
I like the market place stuff but really you can't ever tell what kind of scam you're getting into there. I've learned that you never want to respond to a kitchen aid mixer advertisement.
Facebook is always running 'sponsored' ads, which tend to be companies pretending to be Bed, Bath, and Beyond, or Home Depot or Clark's Shoes or Lego, or something recognizable, like that. But they are not. They are some fly by night company, usually from China and they are trying to rip you off. (Shameful admission: I was ripped off twice by this. Don't ever order from a facebook ad, advice learned the hard way.
You never know who is watching you. Why would I put info out there for people who don't even like me?
Upside of facebook?
I'm going to miss some folks but they can always talk to me on messenger.
Tonight, I deactivated my account.
