Thanks Umair for pointing this out!
For awhile now I have been using social networks less and less without being able to really put my finger on why. I think you nailed it on the head.
Being in the technology space I always thought that attaching your real identity to the words you say would lessen the abuse and to a certain extent it has. However, it still seems when people hide behind a keyboard and screen they are still much more hostile than they are in person.
