This is awesome—a data scientist analyzed rapper's vocabularies against Shakespeare's to determine who had the largest vocabularies. The answer? Unsurprisingly, Aesop Rock followed by Wu-Tang Clan. Wu-Tang? Inventing words? Obviously.
Anyway, the site is really cool. You can peep the map organized by region, as a whole, or (haha) just the Wu-Tang. It's interesting to see who ends up where. E-40 and Outkast, with their propensity for creative use of language, are close to the top. And regionally, it's also fascinating to see that Outkast is one of the only southern rap crew to be a the top of the heap. The coasts on the other hand, are more playful with language.
