I’m very down on Facebook nowadays. But because of the way it’s algorithms interfere in my communication with friends: I don’t know who will be shown what message. So they aren’t messages, they are “contributing content”. So it’s not commmunication. But I don’t get all this obsession with privacy. I’m just not interesting enough for that to be a concern.
