Prediction market for News and tweets

Prediction_markets are speculative markets that can predict outcomes. Can u predict whether a newsitem will turn up on Techmeme/Slashdot/Digg/Reddit/Twittertrends/Buzz/Zeitgest... Can you predict how many tweets it will get by a particular time

If u can, then buy low and sell high...You buy and sell karma points... 

This will help spot raw news much earlier than even twitter...

It could even end up being a Facebook game with real money
