I'm still suspicious that this kind of voting system will stay being of much value once wisdom and the refinement of it is outnumbered by special interest groups.

I don't think we disagree substantially on this.

We do seem to have have a different picture of the the likely influence of public voting if it were to replace anonymous voting. From what you are saying part of this difference would seem to be due to differences in the way we account for the social influence of negative (and even just different) social feedback. A high priority for me is minimising any undesirable effects of (social) politics on both the conversation in general and on me in particular.
