"As Rebecca mentioned above, many have tried to build open peer review platforms and one thing we know is that putting articles up and hoping they'll be found by the right person just doesn't work. There are too many articles & too people who have something worthwhile to say about any one given article. Additionally, the people who have the most to say have the least time and inclination to do so, particularly on a site which is new to them. That's why I think Pubmed Commons has the best chance among non-journal platforms." - Mr. Gunn
