Ahh, thank you for the reminder! I just edited my post to add a link and I added this too while I was at it. :)

I did know about it and I do browse it for reviews -- although, honestly, I've got such a total backlog of things to read right now that it's mostly browsing to see what other people thought of books that I've already read. That's the main reason why I haven't signed up to read the 50 books, too -- because I'm trying to make a dent in my backlog of unread books before I go buying more. (Though my resolve is not working so well, due to my tendency to impulse buy ...)
