Heh.  You know, there's probably nothing wrong with having a recommendation engine for Hacker News.  After all, the frontpage is still the frontpage, so people can use the recommendation engine without it degrading the quality of the site, because most people still use the front page.  This could be a great feature for power users of HN.<p>Of course, there's a problem if <i>everyone</i> switches to <i>primarily</i> the recommendation engine, but that's unlikely.<p>One thing, though.  You should really display the points-to-comments ratio.  Unless a submission seems very interesting, I'll usually ignore it if it has more comments than it has points.  (That does not apply for "Ask HN"-type posts though.)
