Honestly, Imgflip is a better place for venting frustrations.
Maybe I'm old but I just used Facebook as if it were a digital address book. I used to keep tons of notebooks with that information for years and it always got cluttered with updates that, for a time, it was nice for friends and family to update that stuff for me.
My phone does most of this already without the need of Facebook. Profiles for friends and family built into it. So, now it's even less used and just more of a source to reconnect with old friends or family who've fallen out of touch for one reason or another. Allowing us to connect through other avenues or simply stay somewhat distantly connected.
It's also good for "Hey, needed a new phone. Here is my number..." which for a time, a lot of people would get new phone numbers almost every year to every three years. It was very annoying. Most phone services now let you transfer your previous numbers which has cut down on that a lot. It's also a a less annoying way to announce things like parties, funerals, weddings, or reunions without being tagged in someone's text list which pings every message in the group like a singular text message. I hate that.
