but there is a middle ground there, publishing the anonymous reviews as well, and having the ability to comment on them,
I think that even if the reviews stayed anonymous the mere fact of having them published would lead to an increase of their quality.
At the same time of course this in turn might have a negative impact on the rate at which people accept reviewing duties. It could be discouraging to some as it might feel as one would need to do more work.
That blog post is a nice example of sensationalist headline grabbing (I know you didn't write it, so that's not directed at you!). Heng Li wasn't actually "found" anything. He just got in a spat with a reviewer who started calling him names (i.e., "scientifically dishonest").
It would sound very different if the headline was: Mapping God Called 'Scientifically Dishonest’ by Anonymous Peer Reviewers
Or even just, "Author and reviewer have a row" :P
Disgruntled Reviewer Sinks Paper, News at 11
If it were actually a nightly news promo, it'd be more like, "What you don't know this reviewer could KILL you! News at 11". I guess that'd bump the sensationalism up a notch.
