Anyone interesting in co-authoring a book?

Freakonomics Blog » The Man Behind Tyler Cowen, and Freakonomics Too:

FWIW, I am constantly surprised, and a little bit saddened, that more books aren’t co-authored, especially between academics (who often have great research but subpar writing skills) and writers (who spend their days trying to write well but who aren’t necessarily sitting atop a mountain of interesting research). Can somebody please do something about this?
