Leonard and I have started watching The Legend of Korra, which is fun. In one episode, a character says to the guy who's just arrived, "Oh, hi, 'Shady' Shin." And then proceeds to let Shady hire him for a pretty sketchy job.

Leonard said that, as a rule, he would not become business partners with someone who's commonly known as "Shady." I asked whether Eminem counted; Leonard replied that for Slim Shady, "Shady" is a surname, but in any case, Leonard would insist that some non-Shady collaborator be involved. And besides, he said, what might Eminem even want to hire Leonard to do?

I said: a Twitter tool. Specifically: sometimes people tweet bits of Eminem lyrics (without attributing the song or artist), or incorporate snatches of Eminem lyrics into the sentences of their tweets, and so we'd want to monitor the tweetstream to find those, and analyze whether those people are "influencers" (and whether it's likely they and their followers buy music or pirate it). And then, based on that data, Eminem could forecast trends in sales of his music, and hook that forecast up to his investments, to automatically change his strategy towards riskier or more conservative options, as appropriate.

Leonard had been nodding this whole time. I finished: And the name of the tool could be: Increase Mathers.

(Incidentally, in other Korra-rap relations, a big reason I got interested in The Legend of Korra was this fanvid set to "Mama Said Knock You Out" by LL Cool J.)

(Also, Eminem's clothing line of course ought to be "Cotton Mathers".)
