I joined FB to keep up with my daughter some years back. I have found it useful to keep up with friends, old and new, former classmates at various places of higher education, parishioners from the various churches I have served. There are also many shooting and gun friends. I don't accept or keep "friends" who are argumentative, profane or trollish in behavior. I prune the friends list on a regular basis. It is a good platform for me to continue what I have been doing for a very long time. I have never had any problems with FB censoring anything I have posted. However, I do have a number of older "church ladies" for friends and keep the place clean and tidy in respect for them. I post quite a bit of Christian related material, political opinion and just general observations of the country, the world and all it's inhabitants. All in all, it has proven to be a good place for me.
