You are not alone to quit Facebook. Interestingly enough, I posted this blog post a few days ago: https://numericcitizen.me/2018/12/09/my-numerical-citizenships-doesnt-pertains-to-facebook/
I’m putting the final touch to my Facebook farewell post… I don’t know when exactly I’ll quit, but it will be in 2019. People forgot that we could get in touch with each other before Facebook. I’ll remind my “friends” how to do it.
