I think people are being a little harsh on this 2012 thing. I mean, sure, even the Mayans weren't saying the world is going to end then, but why should that stop me from having a big end of the world party? As a bonus, if the Mayans turn up and say "hey, who are we to decide what our culture is? Lets end end the world so those people who predicted it don't look like idiots" then I'll be partying with my friends up until the last moment. Win/Win situation.
Events like this only come round every 8-12 years or so, so make the most of it!
