This is the same for me. I feel obligated to maintain an account and check it once in a while since I have a lot of family and friends who aren't local who do still use it (though most have transitioned from using it as a way to update people on their lives to using it as a place to effortlessly repost memes), but I'm incredibly put off by Facebook's increasingly irrelevant and desperate attempts to get my attention.

Notifications used to be things I cared about, these days they are things like "This person knows a person who is the mother of a person on your friends list. Add Friend?"

I just block the notifications now and log into Facebook every couple of days in a browser and quick scan the feed.
