My favorite part is how people in the public eye who present end-of-days predictions always have some weird excuse after the fact. As was beautifully parodied in Parks and Rec.

In this case there have been impersonators, and the original author has no connection to a lot of the newer stuff. She is not trying to cash in or play things up, which is a wonderful contrast to a lot of people who claim to be doomsday predictors.
