There's been an interesting conversation in the editorial board of WikiJournal of Science of a case where an article had previously been submitted to another journal, received peer reviews, gotten declined, and now submitted to WikiJournal. Points raised include that the reputability of that other journal can be taken into account in accepting their peer reviews, and it seems unethical to omit important comments previously raised. Yet, we cannot ignore our
peer reviewer criteria. It seems we need to know the identity of the peer reviewers in order to make this judgement. I think this is further necessitated by the fact that we may want to complement the peer review, and we'd risk asking the same reviewer a second time if we don't know the identity of the reviewer.
