With so many SEO articles I find that it's all so incredibly gimmicky and formulaic. It's more about writing link bait to get link juice and build traffic than creating and sharing quality content. For that reason I would rather not see HN become a resource for furthering that pap. There are likely some SEO articles that fall into the latter category, and I wouldn't mind seeing them here from time to time...
That said, this one belongs in the former.
