You can spend a lot of time creating content that you think HN is likely to like, and submit it at the optimal time, and still not get much karma unless that entry gets picked up within an hour. Otherwise it's just pushed down and out, and your time has been wasted (assuming the goal is to get karma). Since there is a degree of luck involved in getting to the front page, I hypothesize that you can leverage the law of large numbers to maximize your chances of getting karma by also submitting HN-targeted content regularly/frequently.
