First: I love this service especially since I am a MacUser and the only alternatives I found so far are offline .exes. Thanks Ryan.

What would make it really perfect would be if it would recognise duplicate pages not just duplicate words. Sometimes the content is the same on the home page - direct link and then on an .index page. Or there is similar text with different pictures.

Most translators don't want to discount similar phrases because you still need to study and adapt for the context, but if the whole paragraph or page is the same then one might deduct.
