I got lazy after adding One Piece, but I wanted to show you this:

It has Japanese UI, but you'll understand it. ONE PIECE!! xD
Basically it's a same thing as Amazon.com's Listmania, but it has more feature. This one is still in development, so I'm hoping they'll add more stuff in the future.
You can add your own reviews (85 chars maximum) and you can have Amazon.co.jp's associate ID tied onto your bookshelf so if somebody buys stuff through your link, they'll give you some $$ back.
Now my question is… ... Do we have something similar in English? It doesn't have to have all those cool bookshelf UI as long as it is very organized.
DVD version of it will be:
