I remember an old quote of AnonyMints: "enable the free market to experiment and innovate. Don't try to proclaim you know the perfect design for all" . I think his matter-of-fact frankness and thirst for engineering what he feels is a fix to as yet unsolvable problems gets mistaken for him arrogantly forgetting the latter portion of that quote whenever he criticizes existing approaches.Of course it is easier to identifiy flaws than it is to propose a solution avoiding them, or indeed presenting another set of flaws. Harder so to successfully implement said solution so he has to get some props for open his project up for scrutiny.
