We need to reward the 'thankless job' of substitute teaching with better pay and chances for permanent positions. I look forward to the day when no student comes home saying, 'I didn't learn much today... we had a sub.'
None of my friends don't have Facebook accounts. Op-eds and studies can highlight our decreased enthusiasm for Facebook 'til the cows come home, but it doesn't change the fact that we are chained to the beast. Voluntarily, of course.
