Many of these suggestions are being attempted in journals like PLoS One (plosone.org) or through groups like Faculty of 1000 (http://f1000.com/) for commenting/discussion. Many journals now have comment fields on their articles, and you'll notice that most of them go empty. All the discussion happens behind closed doors before publication in anonymous peer review. Nobody wants to stake their reputation on something not polished.

edit: I partially take-back my suggestion of Faculty of 1000. Apparently, they are not open to unaffiliated and require a subscription. I like what they're doing, but it shouldn't be so ivory-toweresque.
