Same for me. My departure was compounded by a couple of obnoxious ultra-right-wing jerks who posted crap that just made me sick. For my sanity, I just dumped the whole thing, and I don’t miss it at all.
I have a FB account and use it a lot, which is pretty rare I think, for women of my age (58). At least, none of the friends I used to work with or go to school with have accounts or they are difficult to find because of name changes etc.
I like it. I can keep up with friends I don’t see often because of time constraints or geography. I can see photos of my friend’s newest niece born in New Zealand and pics of her latest hairstyle. (The friend, not the neonate.) I like hearing that my friend in regional Victoria’s son has finally had a haircut and posted a photo to prove it. Way too trivial to bother sending an email with a photo attachment but the sort of thing we’d laugh over if we lived close enough to each other to get together for coffee.
I don’t have three thousand friends - only people I actually know and like - but I do wish my cousins were a bit more findable. I think I must be getting more nostalgic as I age.
I love facebook and am on many times a day. Besides my personal use, I also use it quite a bit for work; part of my job is to update my organization’s fb page.
I don’t have one and never will. nothing in my life is interesting enough to warrant posting anything about it. The few people I care about I see on a regular basis anyway, and there’s no way in hell I want to “re-connect” with anyone I went to school with.
I just went to school for social media marketing. I damn well better have a Facebook account. 
I also have Twitter and G+ which I use regularly, and LinkedIn which I use intermittently (and then only because I’m looking for work).
So that’s where you disappeared to. Well, that’s a relief! I thought you’d unfriended me. 
I got sucked into Facebook while I was living on the west coast as a way to keep in touch with the many cousins I had back on the east coast. I keep my friend list pretty small, always less than 100, usually around 60-80, mostly family (about 3/5). I log in a few times a day to keep up on whatever movie quote status, who can provide the funniest/most inappropriate caption, etc we have going on.
So how do you have your settings? When I go to “Notification settings” I get fine-grained control over notifications for pretty much everything that happens on Facebook apart from messages, which is the only thing I actually want (I missed a couple of really important messages recently - and even though I have told said friends to email me to ensure delivery some persist in using FB instead).
Ah, found it - it’s under “All notifications” > “Facebook”. Jeez it’s absurdly complex.
I created one when my kids wanted pages. They could have theirs but the requirement was that they must friend me. I think I’ve posted to it about 5 times over the last 5 years and I posted pictures once when I renovated my office and wanted to share with some coworkers and friends. Now the kids are all grown up and do not need monitoring.
Have never been interested in Facebook. This site already takes up too much of my time. The wife has one though.
