It helps me organize events and keeping up with events of my friends. Or for just keeping up with friends I can't meet at the moment. It is useful tool. Sorry, I said it. I'm getting annoyed how people like you are always eager to blame facebook for their inability to actually improve their lives with it. It is really easy, so stop the excuses and learn something new. You might realize why people use it and maybe finally appreciate it.

Or learn how to actually make an alternative. No, Mastodon is not even close to it.
