I think it is a good idea..if not the post-peer review we can have a platform where the researchers can comment on the published papers which will help both the audience and the authors of that publication..lookslike the open-access journals have this option..do they?
Yes Dr. Satyanarayana, I suppose they do have such options for post-publication peer review, which is a good idea to cross-validate observed result and to question the author on other aspects of the post-review process. Like a forum to discuss implications, any short-comings, future directions etc. Mostly the open repositories and open access journals as well H-indexed scopus journals are having these options as peer review commentaries.
