If everyone starts dropping their "relevant content" in the comments, most of it won't be relevant, and a lot of it will be spam. People don't have time to sift through hundreds of links in the comments and tens of thousands of words when the whole point of HN is that discussion and curation work in the opposite direction.
If your content is good, someone else will submit it as a story. Your blog is probably already read by thousands of people from HN, if they think a particular post belongs in the discussion in some comment, they'll link it. That's why other popular HN users who blog don't constantly promote or link their own content here, unlike you. They know that you don't need to do it yourself, and doing it repeatedly sends the wrong signal (which is obvious and plenty of socially aware people have already pointed out to you in multiple threads).
Trying to normalize that kind of self promoting is like normalizing an annoying mosquito buzz, most people simply don't want it and no amount of "normalizing" will change that.
