Maybe a counter at the top of the page (karma, counter) to show how much time someone has spent on HN in the past (day, week, #{interval}) guilt-trip (some) people into spending less time on the site? Or with the number of times they've opened up a page to HN? // edit: This is a social/mental problem, not a technical one. I'd be surprised if a complicated change did anything to fix it. Noprocrast works because its simple. Changing algorithms around isn't as obvious, any behavior changes as a result would probably be much more subtle to observe.
