I'm going to post this request at a number of econ blogs I read, in case others have suggestions.

I'm feeling, rather desperately, that we need a faster tool for critiquing and comparing the different proposals out there. I want a mechanism by which the experts can point out flaws in different solutions and arrive at an optimal selection (if not consensus). If this all has to happen in a week, the blogosphere needs to be even faster than usual.

Is there a site out there doing that now? Could wikipedia support this, or would the comment threading collapse under the weight? Other suggestions?
