I was fairly active on it for a time. Joined because I was a member of a church that used a private FB group as a communications tool and to connect with some other people. Ended up in a few groups. Never engaged me the way the forums do and as the privacy and security questions mounted and FB execs like Zuckerberg gave unsatisfactory (to me) responses to the concerns, I finally pulled the plug. Went back on briefly when I was using Messenger to keep in touch with another admin on my board, but quickly left again. Now I've been FB free for a couple years at least. Don't miss it.
