Arns M. Open access is tiring out peer reviewers. Nature 2014;515:467
According to the author, as numbers of published articles rise, the scholarly review system must adapt to avoid unmanageable burdens and slipping standards. The result of the increased pressure on peer reviewers is that papers are assigned to reviewers who are not experts in the area. The author suggests a two-tier system, in which some papers are not reviewed before publication at all and are instead subject to a post-publication peer review. This would free up peer reviewers to focus on papers with more direct societal impact, where the question of whether to publish at all is more relevant.
