Simply described as: Tag Mirror: What LibraryThing thinks eoinpurcell is interested in this is a pretty impressive feature and one that is of enormous use to just about everyone from publishers to readers.

There is much more in Tim’s blog post here:

Tag Mirror “holds a mirror” up to your books and to you. Instead of showing what you think about your books—what a regular tag cloud shows—it shows you what others think of them, in effect using LibraryThing’s twenty-two million tags to organize and surface interesting topics from within your own collection.** As with other tag clouds, size equals importance. When you click on a tag, you get a relevancy-ranked list of books tagged that way.

Tagtastic?
