OK, this is very much slashdot moderation I guess ;)
I never really thought about that possibility, as it is today, the only concern is about visibility. You boost or decrease an element’s visibility. No categorization.
Could tags do the trick?
Maybe another kind of categorization could be done through electoral lists. As a user, you would decide to follow the recommandations of a bunch of people which you consider funny, or not depending on what you want! In fact you could even constitute your own electoral list, integrating people whom you know you love the votes!
But those electoral lists are not yet done. And they look quite complex from a performance and interface point of view.
None the less, what do you think?
