Emily Post may have taught your grandmother that the salad fork goes on the left, or that "May I present" is better than "May I introduce" when it comes to formal introductions, but recent headlines seem to indicate there's a whole new list of etiquette rules that need to be applied to social media in the digital age.

They don't go to the beach, the beach comes to them." after the March 2011 earthquake and tsunami in Japan. Whether you thought his jokes were funny and just Gilbert being Gilbert or they were too soon and grossly insensitive, there's no question they cost him what was a lucrative and high-profile position as the Aflac spokes-duck.
