I heard Abby Blachly, a Librarian from LibraryThing speak on Friday. She gave a great demo of the site, pointing out features I didn't know it had and really got me intersted in it. I've had an account for a year or so and really never did much with it but this weekend I spent time adding more books, looking at the tools, reading group posts and viewing the profiles that have many books in common with me! It was pretty compelling!
