The reason that everyone got so excited about the Mayan end-date is that it is a major culture's doomsday prediction that is testable in our lifetime. In the Jewish tradition, the messiah is supposed to come in the year 6000 AM and rule for another thousand years until the year 7000. Thus the world lives for a cosmic week ending with a sort of cosmic sabbath of messianic reign. Now that would be a nice prediction to test, unfortunately the year 6000 in the Jewish calendar is about 2240 AD. So just like all the people before us, we won't be able to see whether anything happens or not. Here we had a prediction that was to mature in a couple of years, and these spoil sports had to ruin our fun. Of course doomsday predictions are only fun when they don't come true, so seeing when the ice caps finally melt or dollar collapses doesn't have much of a pay off when you're eventually right.
