Tag Mirror

Ok I was cruising on LibraryThing.com and there is this new way of tagging my books. It is called tag mirror. Instead of just my tags showing, the whole LT community will show their tags on a book. LT already has over 27 million tags from the users on their own books. Tag mirror will depict the whole communities tags on one book. LT does provide something like this already if you click on your book's page but here you will see everyone else's tags right under your cloud tag. I have to say this sound interesting. Every time I go onto LT I find something new. Here is a blog on LT discussing tag mirrors.
