Without realizing it, Facebook users have upgraded their minds. By simply using the platform, users have gained the ability to communicate with everyone they've ever known at once from anywhere !
In the past, friends, teachers, collegues and family were all interacted with seperately. Upgraded Facebook users now talk to all these groups at once and are accepting this as normal.
Personally I find this trend very disturbing. Human interactions are meant to be seperate between groups. Now there's no room for error as you have to try and please everyone all the time. Political correctness is the side effect which has become fashionable.
There's an old saying, if you try to please everyone, no one will be happy.
