That's too bad. I'd especially like to see how it'd work on comments, where I'd try to teach reddit to avoid in-jokes. As for Amazon, maybe its recommendations

That's too bad. I'd especially like to see how it'd work on comments, where I'd try to teach reddit to avoid in-jokes. As for Amazon, maybe its recommendations are intentionally unrefined, like how Target discovered it needed to obscure its direct mail campaigns aimed at newly pregnant women ( http://www.nytimes.com/2012/02/19/magazine/shopping-habits.html?pagewanted=9&_r=1&hp http://www.nytimes.com/2012/02/19/magazine/shopping-habits.h... ). Granted, it's plausible Amazon just hasn't cracked the code yet.
