"The model can only get better with more training data, which requires me to judge whether I like stories or not. I do this occasionally when there’s nothing interesting on Facebook. Right now this is just the above command-line tool, but maybe I’ll come up with something better in the future." If you let your program log into HN using your account, it should be able to tell which of the stories you've up-voted there. If you use that as the input to your classifier, as you read stories on HN, simply mark those that interest you by up-voting them. I'm also curious to know whether the stories are weighted by age to account for changes in what you find interesting.
