It looks likes Nature has gone the way of the 21st century and will place preprints of submitted but not yet accepted papers on their servers for public comment to assist the normal peer review process. I think this is a good idea, but the only real issue is getting the public to notice that they started to do this in the first place. The problem with any good on-line idea is gaining the traffic to see your wonderful idea utilized. For example, I wrote a nice script that will nicely format some elementary information of the known isotopes from the most recent atomic mass evaluation 2003, but no one really knows or utilizes it.

http://www.nature.com/nature/peerreview/index.html . You can check out the preprints already posted from this link
http://blogs.nature.com/nature/peerreview/trial/. The site diplays articles in blog format. And since I didn't stumble across this myself but read it from Everyday Scientist you can see their post about it from here

Finally, since Nature is posting preprints in blog format, we would be able to add these preprints to our forum feed and they would be made more visible in case anyone wanted to comment on them. If you want them added to our forum feed please post here to let me know.
