Life must be filled up

Has anyone else had a look at Book Rabbit? It seems to be attempting an amalgam of a book shop and a LiveJournal-style community. The page is a horrible mess! They don't make it very clear exactly how you are to join up. There's a so-called helpful video here but it's clear as mud as far as I'm concerned.

I'm not on LibraryThing and I wasn't seriously considering BookRabbit; it just seemed an interesting idea. I see someone has posted a photo of a colour coded bookshelf. What think you of that, ladies and gentlemen?
