I'm curious how many commenters here who are making strong statements about the worth (or not) of peer review have actually participated in it both as author AND reviewer? Or even as an editor who is faced with the challenge of integrating and synthesizing multiple reviews into a recommendation? There are many venues available to share your research or ideas absent formal peer review, arXiv/bioRxiv being among the most popular. If you reject the idea of peer review itself it seems like there are plenty of alternatives.
