When Dubner Talks, People Listen

Well, at least the folks at the PopSci Predictions Exchange listen.

Last week Dubner blogged about Jatropha, a weed that could spearhead a biofuel revolution. At the end of his post, he urged the PopSci Predictions Exchange to launch a contract on Jatropha.

Voila.

So far there are only sellers — people betting against Jatropha — and no buyers.
