Tagish Amazon feature

Tagish Amazon feature:  Via Marc Hdlund (Signal vs. Noise) blogs that Amazon has added concordances and statistics about the text of a book to their site (definition of concordance).
Marc observes the cordance looks like a visual display of tags, but the
words don’t work like tags as you can’t find other books with the same
frequent words. (Another new feature, “Statistically Improbable Phrases,”
does allow you to find books with similar language, as long as the usage is
improbable.)
