A delightfully recursive peer-reviewed symposium on peer review. On the bright side, it does use at least three different forms of peer review in reviewing the papers on peer review so I guess you might expect some very high quality papers as a result. And if that didn't happen, then the symposium will have at least proved the need for a symposium on the subject.

It would be very interesting were the participative peer review process to lead to changes in the participative peer review process. If one of the rules of change is that the rules of change may change then things can get very interesting.
