Some cool predictions sites

www.longbets.org...
It's a website where people make well-reasoned (non-psychic) predictions & place bets on them. Of course, it is no Nostradamus.

You can also get a bunch of older predictions, including the complete Nostradamus, here:
www.sacred-texts.com...

And would one of the numerous "Dead Pool" sites be considered predictions sites? I guess so.
