If people on HN care about cost effective ways to build traffic, there are few better options than SEO. Have no money for marketing but have a great app, useful content, and a creative flair for promoting it? Then look at SEO. And that starts by understanding the SEO means: a) how usable your site is for bots, and b) how you can attract links to it. If SEO doesn't make sense for your business, ignore it the same way I ignore posts about Haskell and Lisp. I have nothing against them, that's just not my platform.
