Enlist in the Book Army

I was sold on the idea of Book Army when I saw it described as like a Last.fm for books. It’s still in beta but the idea is that you tag books you’ve read, rate them and write a review (if you feel so inclined). The site will then start recommending other books you should like. I’ve found a few bugs so far and the site’s just gone down for maintenance but I have high hopes that, if they listen to feedback, find a better way of bulk importing your past reads (is there a secure way of getting your Amazon history output?) and get the right tech team behind them, it should be a winner (and make someone a tidy profit when they sell it to one of the major players).
