Mr. Harold Camping threw up some billboards and made enough noise to attract media attention for his predicted date for The Rapture: May 21, 2011. Mr. Camping is a Christian broadcaster who gives a bad name to both groups, which in this day and time is pretty hard to do.
Now, I think that The Rapture and The End of the World are technically - er, biblically - two different things, but let's give Mr. Camping the benefit of a doubt on this. And he did manage to push Mississippi floods, DSK/IMF/Sofitel NYC, Arnold Schwarzenegger, and Osama Bin Laden out of the prime news spot for the past week.
