Yes, this is such a good point, @danny71st! You should do that post!
Facebook seems to be about constructing and feeding a false image of your "self," which of course is total bullshit, and not about real communication. I agree that fear is the main reason for this.
Personally, I have family members who simply won't consider some of my more unorthodox ideas and get extremely upset whenever I mention them. I don't think I'm going to change their minds, and I don't want to hurt them by bringing things up over and over, to no avail.
If it weren't for these few people, I'd blog about important stuff on Facebook too and just let the 'friends' list adjust itself.
