I browse /. at +5 (and see only very good comments) except for the once a month or so when I get given mod points.<p>15 minutes a month of moderation per person seems to be sustainable/scalable, because it's been working for ages and I have noticed no real change in Slashdot's +5 comment quality.<p>Where that fails with HN is that we have infinite mod points all the time, which:<p>- Encourages point inflation as the community grows.<p>- Discourages people from taking moderation seriously as if it was a big deal you wouldn't be able to do it all the time.
