I'm fairly transparent, as far as my identity here and other boards. I use my actual name on a couple boards(one 'requires' real names, though many people get away with fake ones)
I don't share any personal stuff on any internet sites, I don't see the point.
I don't start drama or share it.
FB for me is mostly dog stuff, and I just scroll past all the political/gun rights and other filler. Unless it is really funny, then I may even share it!
