Annual awards for prediction markets

Which prediction markets ("information futures") had the best year last year?  Worst?  Which contract performed the best or was the most interesting?  What was the best academic paper in the area?

Find the answers to these questions, and many others here.

Thanks to Robin Hanson for the pointer, I will note that Robin was named (deservingly) as person of the year in this area, even though he bet Saddam would not be captured.
