I did something similar ("50 terms most predictive of a submission making it to the front page") some time ago: https://news.ycombinator.com/item?id=10893677 https://news.ycombinator.com/item?id=10893677 . One realization was that it was easier to predict if a title/keyword would NOT make it to the front page than if it would. That is, it's clearer what to avoid (startup, app, business, product, mobile, marketing, etc) than what to do.
