Discussions on HN are never strictly on topic. There are always lots of meta comments, and many very good comments I've read were only tangentially related to the submitted article. Instead of complaining what HN should and shouldn't be, try writing good comments, upvote good comments and downvote or ignore bad comments.

Also, if you read the article, you'll see that the author talks a lot about SEO and conversion optimisation, and chmars' comment fittingly points out how annoying it is when people go overboard with conversion optimisation.
