A friend of mine turned me onto a new web site called goodreads.com. It allows you to group books you have read or want to read onto shelves and share reviews and discussions with friends. I signed up today, and it looks pretty good so far. I think the hardest and most time consuming part is just trying to enter a lot of books to fill your shelves and start writing about what you’ve read.  Kind of time consuming, but useful to someone nontheless.
