May 20, 2010, as we all know, was the worldwide e-event occasion of "Everybody Draw Mohammed Day". It drew global media attention, but, according to a quick perusal of its Wikipedia article, not much else, and certainly nothing of note for the same date in 2011.
Now, I always felt that the concept was half, or maybe three-quarters, of a great idea. Who doesn't love a good-natured poke at religion, provided that the pokes themselves aren't themselves hateful or otherwise inspired by bigotry? (Is not "Life of Brian" one of the funniest movies of all time?)
Where I thought that the idea fell somewhat short, however, was in singling out Mohammed, and thus Islam, for fun. Why not have an "Everybody Draw Moses, Jesus, and Mohammed Day"?
Because plenty of people have drawn both Jesus and Moses over the centuries and never had a Jew or Christian issue a fatwa in response. There's no challenge in it.
