I cannot perceive a difference between g+ and fb - can somebody explain?
Let's take this vaunted 'circle' concept - it's just fb friends groups, which was always possible to be used (although perhaps not as obvious to most people)

you can make a post and make it visible to xyz circles, but not change those xyz circles after the post is made

so if I make a post to everybody and then something not work safe comes up, I can't (now) block the work friends from seeing the remainder of the post

WAT DO
