It's been out for a while, and although it's really promising, a large number of obvious features are completely missing. For example there's no RSS feeds of a user's activity and there's no "per-book" pages (it'd be nice if you could point friends to a page that shows your review of the book, plus the passages you've highlighted/noted). There's a list of books you own, but there's no way to search the list. Also, the "Daily Review" feature is broken (I get the same book every day). I think it could be a really useful site if Amazon would invest in it a little. But it seems as if they've given up on it, since nothing seems to have change since the site was launched. (Also, I haven't seen any review mention it, so perhaps people don't care.)
