note that this is a marketing site (as noted in my other comment[0]), so discount appropriately.

social pressure predates humans. it's pervasive and our teenage years (especially) are spent coping with/negotiating that. the difference with facebook is that it's potentially unbounded in reach and visibility (in nearly all cases it's not, but every once in a while, something blows completely out of its social circle). as with many modern phenomena, the risk-aversion this induces is out of proportion with the actual risks because of that potential (but not actual) reach and visibility, amplified by memetic social networks that trade in novel (whether true or false) information. in short, the worry over the effects of offense are greater than the potential effects themselves.
