The only thing I regret about not having FB anymore: I don't know when peoples' birthdays are.
For the entire history of humanity, we didn't know anything about anyone's lives unless we saw or talked or heard about them. I don't consider it a loss to not know distance acquaintances' life updates...if it's important, I'll hear it from other FB users or from an important friend.
There used to be a way you can populate calendar apps with facebook birthdays. I still have it from a decade ago but I don’t use the site enough anymore to know how to do it again.
