I think Slashdot has a pretty fun model, if you are referring to the point system. My favorite moderation model so far is SA's, because it actually adds value instead of merely deterring vandalism. That's also why seeing pg post here is nice.

It is very much my preference, but I do think that ultimately we'll be able to show and justify that gated marketplaces of ideas are objectively bad (as exemplified by community-created filter bubbles, etc.).

Edit: No idea why people are downvoting you. You raised a few good points for discussion. C'mon HN. :(
