I've never really scrolled through the frontpage, I don't look at people's posts and photos, happy to message them through text or WhatsApp, but I absolutely need the events. Without them, I'd lose so much touch with all but my closest friends.
People tend to respond to this concern with "if they don't invite you individually they aren't that great a friend" but that's my point - they're not, but they're people I like and I like to see them a few times a year at birthdays and other celebrations, and I'd feel my life diminished if I didn't have them. But there are dozens, I don't have time to catch up with them for coffee, and I don't honestly love the pressure of one-on-one time with people who aren't very close to me, anyway.
People who advocate deleting Facebook, do you not have/want such relationships? Or do you not care for catching up in that way? Or do you have some solution? Because for me it's the absolute core feature of Facebook.
