Shelfari is a friendly online community that goes beyond Amazon’s basic ratings, reviews and recommendations, letting the user share what’s on their shelves in a more personalized setting. The book-centered social network lets people make contacts and discuss the books in their lives with new online friends—much like a book club. It gives you the opportunity to, say, discuss the new Harry Potter book with a bunch of Harry Potter fanatics without having to actually let any of them into your home. Meet bibliophiles from Beantown into Baudrillard, or get connected to someone to proofread your “Scooter” Libby fan fiction. It’s a marketplace of discussion for nerdy bohemians, serious academics and the casual beach-reader alike.
