Rohitash - an interesting notion - but I would personally not want to see that. I think that most readers would 'ignore' the extra content - unless they had 'an axe to grind' i.e. were the reviewers mixed, correct, wrong etc. I review for over 40 international peer-review journals. I put forward my most considered response to benefit the eventual publication - whether in the intended journal or elsewhere. I may not get it 100% correct each time - but my feedback is based on a great deal of experience. Public exposure may invite criticism and critique of the review process. Personally, I wouldn't mind that - but less experienced reviewers might be put off reviewing if this was to be the case. 

 The reason this is important is because academic journals are constantly being hijacked when editors send papers to known reviewers who may make decisions based on nationality or community. You may find that in some of the top journals, not so novel idea papers are published through such review process. I would like to see names of reviewers published along with the papers. At least this will give more motivation for reviewers.
