Since the members of Earth Destruction Initiative didn't agree on how to destroy existence, they postponed the doomsday from 2012 to 2013.
Like the C++ ISO working group, when the release date approaches they delay it by an year or so. Earth destruction is a big challenge as well so it require some preparation.
The project of tuning the CERN LHC into a black hole has failed so they need to figure out something else
@Seraphimsan,
No, that's a rule of 4chan, not the Internet. The rules of the Internet aren't like the rules of a website, they're more like the Laws of Science. Also, rule 8: "There are no real rules about posting".
@QWERTYman,
The actual event is not to do with graduation, although that may be how they chose that date. What are you graduating? If it's university, then I really doubt that most Ebaumsworld users are in university.
