In an earlier post, I mentioned the growth of online peer review. One of those sites, Faculty of 1000, provides post-publication peer review. Content experts evaluate published papers and score them based on how importance.
The site has now expanded to include reviews of posters at academic conferences. 
You have to register to read the evaluations, but any user can scan the submissions. And it’s another avenue for faculty to demonstrate the reach of their research.
Traditional peer review seems fairly entrenched for journal submissions, but when it comes to posters and conference papers, the web provides a universal platform for disseminating ideas.
