Book RX - Recommends books from your Twitter feed

Here is a very cool web tool from Northwestern University called Book RX. This website will generate a list of book recommendations by analyzing your Twitter activity. The site works best if your primary language is English and it does tend to recommend best sellers over more obscure books. Book RX could be good way to come up with book ideas for yourself or you could use it to find gift ideas for friends and family who love to read.
