I use FB to communicate with friends & family. That's it. Most of them post very, very seldom, and the really chatty ones, I just mute. Most of these people, I'd never hear from and they'd never hear from me, except for FB.
Whenever I read about FB's treatment of news, politics, and vax (mis)information, I think "why are you going to FB for that? There are a zillion better places on the Web."
Twitter is better for getting the political Zeitgeist. RSS is not dead, contrary to what you might have heard, and Feedly is thus better for almost every kind of news. This site, Stack Exchange, and Quora are better for more intelligent commentary. Why would I even try to use FB for any of that?
My cousin Ray had been (I thought) permanently estranged from his family, and he finally reconciled with them. I wouldn't have found out about that without FB. That's what it's good for. It also would not make Zuckerjerk nearly as rich.
