All,
Yaroslav added a short summary of the previous discussion on expert involvement/expert feedback:

My feeling is that we will learn a lot about what may or may not work for this project from the survey that Daniel, Giota and myself are currently preparing (I am happy to give anybody on RCom access to a live preview of the survey, just drop me a line off-list if interested).
How to implement an "expert feedback" system that is at the same time respectful of the community, useful (as in: unbiased and constructive for the editor community) and scalable (i.e. involving as many reviewers and from as many fields as possible) remains very much an open question.
