What's the point of communicating privately, when you can whine and humiliate publicly?
This seems to be the motto du jour of the socially networked classes.
It is simultaneously vacuous and powerful.
Consider, please, the case of a young gentleman who was rather cross at his high school teacher. He didn't tell the teacher why he was cross. No, he told Twitter.
"I hate you, Mr. Torrence," he screeched. "You said the test was in (sic) Wednesday, so give it to us on (sic) Wednesday, not Tuesday. #YouNeedACalendar #ScrewYou."
