Not to make a big deal of this, but I shut my Facebook account and unfriended/unliked everyone on it. I didn’t deactivate it because that would have erased the Facebook Page I maintain for people who want to follow my blog there (with all the usual caveats). Publishers expect FB presence, and at this point that’s the minimum I’m willing to put in.
Instead, I set everything to private, unfriended everyone, including friends I’ve known for 40-some years and my siblings (along with many many complete strangers).
I realize this will cut me off from people I care about, but it was time.
If you’re a Facebook person who absolutely has to follow me there, go to my page, which is in the sidebar of my website.
