Would be very interesting to see this applied to blogs in different categories to rapidly learn languages through reading based on the words that you currently know and the most frequent words in that language. So it would always present you with the article that suits your level and you would have the benefit of learning the most new words.

Also would be interesting to see it applied to newspapers, with obvious slices like particular author, section (sports v world news etc) distribution year to year, and which paper. TV news broadcasting could also be interesting to compare by the same dimensions, though the conversational style in some interview shows would possibly make this less telling. .

That's something worth trying.
