Why do some people seem to have the unfortunate desire to bring down an article by openly and deliberately mocking its possible mistakes? These comments are obviously not meant to point out mistakes. If this was the case, a simple PM to the person that posted the article would be sufficient, no need for ironical highlighting.
Furthermore, these articles are not meant for anyone's pretentious literature needs, they are meant as informative material. Nevertheless, I agree that professionalism and etiquette must be maintained but posts such as the one above serve no constructive purpose or value. I believe that everyone would be highly appreciative if we can all abstain from making such posts in the future.
