I am on Facebook, but have been wishing recently to just get rid of it. I mainly use it for chat and for groups. I am the social media person for 3 separate things in town so I need to keep my account active to admin those. I'm in some social groups and a support group for ASD children but I'm leaving that shortly as it's not overly supportive. But I do like my little social ones. They have been weeded down from much larger groups so only have the good ones left. I use that chat thing a lot as I moved 10 hours away so it's a super easy way to keep in contact.
On my phone, I have the FB app somewhere buried in a folder, I only use the Chat and Groups apps, not the actual Facebook one.
I have been checking on their lately for flood warnings etc. most of my "activity" on my own page, comes from other apps, just stuff for my far away family and friends. I just hit share from other apps without actually going into FB.
