In my opinion, the slashdot system is complicated and doesn't seem like it would be worthwhile here. One of the (theoretically) nice things about the slashdot moderation system is that it (usually) serves to hide trolls, spam, etc - important, because slashdot does not (ever?) delete user comments. BF does - we're lucky enough to have mods that would get rid of real spam/trolls very quickly.
