Thank you for this @chinito. My views on comment are that they are meant to either criticize the views of the post, question the premise or context of fact or better, add some relevance to the post where the writers knowledge sphere of influence did not reach.

I totally agree with you on this challenge which i hope will spur a good commentary spirit on us and as well give a push for a super-quality post. Thanks to @mermaidvampire for this mention.
