Mobile Content Today just reported a new Gift Finder application that Target has made available for the iPhone.  Line up age, price range, sex and personality, and let ‘er rip. 

How fun would it be to have the same kind of tool for books?  You could have genre, setting, personality or really any number of categories spitting out recommendations.  I think it would be an especially great way of getting readers to try out new authors.

Amazon and any number of stores have similar gift guides, but none that I know of exclusively for books.
