What should be a new or improved peer review model, do we need it, and why?
There already is a number of proposed modifications to the existing peer review model, e.g.
1. open peer review, see e.g. http://www.nature.com/nature/peerreview/debate/nature05535.html
2. giving the reviewers bonus points which are later required for article submission, http://aclinks.wordpress.com/2012/02/17/more-on-peer-review-2-0/
3. creating a channel (say, a secure form at the journal web site) through which the reviewers could anonymously contact the authors (and get response from them) in order to clarify something or check some subtle details not included in the paper (proposed by Igor Belegradek at this discussion: http://mathoverflow.net/questions/50947/on-referee-author-communications )
What do you think of these modifications? Which modifications to the peer review system would *you* suggest?
Thanks for your input.
