The Hawaii Project is constantly scanning what the blogosphere is writing about in terms of books, and then matching that to your tastes and interests (topics, authors, website sources), so the recommendations always stay fresh and timely - vs Goodreads, which tends to be pretty static (if you like X you'll like Y). I may not care about all the books that say, the New York Times Book Review writes about, but if I'm into historical fiction and they review a book of that sort, I'll get a recommendation for it.
THP also has an index of articles from the web about particular books, and the ability to quickly browse what sites are writing about - kind of like a books-oriented news reader
It also generates a weekly mail with books that match your interests and authors that are being written about, so you don't have to go looking for them or miss a book from your favorite author.
And yes, my design skills need help :)
