Peer review: from recognition to improved practices

Scientific publishing has experienced profound changes in recent years, such as the advent of open-access journals, the increasing use of preprint archives or post-publication blogs, to name a few. One pillar still remains: peer review as a key ingredient that, in most cases, contributes to clarity and quality, often detecting errors and misinterpretations. Unfortunately, peer review is poorly recognized and good reviewers are rather a 'rare avis'. Even worse, this necessary task in science is generally overlooked in curricula and post-graduate education. Some considerations should help us all to ameliorate greatly our understanding and duties.
