Do we really need comment section on blogs? The blog comments are not particularly helpful to have any discussion at least not the way one can have here on HN, reddit, Twitter, etc,.
Besides the poor user interface, the users have to sign up to comment. Why would they sign up when they can have discussions on above platforms? If one does not implement sign up but allow users to comment just by entering username (like the way this blog did) then people start abusing the comment section.
I think HN/Reddit comment section should be used for discussions although I would prefer if it could be embedded in blog somehow. I understand that this is terrible idea if reddit/hn chose to be walled gardens someday but then do we have other better solution?
