About the possible flaws in the reviewing process, the open-access publisher Frontiers (recently acquired by the Nature Publishing Group) proposes to reveal the names of the reviewers once the paper has been accepted, since they take part in the writing process:

"Frontiers is striving to remove any bias from the review process and acknowledge the reviewers for the significant contributions in improving the paper. To guarantee the most transparent and objective reviews, the identities of review editors remain anonymous during the review period. Only in case an article is accepted do their names appear on the published manuscript, without exceptions. However, if for any reasons a review editor withdraws during any stage of the review process, his/her name will not be disclosed." [Source : http://www.frontiersin.org/Design/pdf/ReviewGuidelines.pdf]
