Same here. Easiest way to share pics of the kids and keep them updated on our family since we live far away. Without my family on FB I would have left a while back.
It's funny, to appease my Mom and others not on Facebook I setup a self-installed WordPress site to share family content. I then notify subscribers via email, which even these days still is an effective communication tool.
It's actually worked (although publishing to it on my part isn't consistent), and makes me feel much better that my content is stored on my server, in a format I control almost completely.
I have a cousin who does that with pictures of her kid, and no one follows the links. She receives less than two unique visitors a month at this point. Turns out we've taught our families to be overly suspicious of 'CLICK HERE FOR XX' advertising and e-mails that even look similar to that model.
I think many of us are finding ourselves in a weird middle ground. The younger generation has moved on to Snapchat/Instagram/whatever to chronicle their lapses in judgement and youthful indiscretions, which used to be Facebook's bread and butter. Meanwhile, grammy's using Facebook to play games and forward me click-bait articles (a modern alternative on her FWD:RE:RE:... emails).
I guess as a working adult, LinkedIn should be my go-to network, but no thank you. Hmm, maybe that's where Facebook is going with this.
