OP here -- ahh the infamous top comment on HN; always good for a great mood killer to an article that was, simply put, really fun to write
You have to agree the comment was funny though.
So you don't think HN's view on SEO is unduly negative then, after all?
I don't mean to put words in your mouth, but I've seen this type of question many times and the subtext often suggests that a need alone isn't enough to justify an industry. It's a service, and one many people would rather pay for than spend their time learning and doing.
Most web site owners are not applying "common sense" SEO strategies to their sites. Many "web designers" don't either.
That's how you end up with an article with lots of upvotes (from the people who liked your artcile) and some rude comments (from the people who didn't like your article).
