You might want to re-read my comment. Nowhere did I say that marketing doesn't matter. Nowhere did I say that you should just build more stuff and not write a resume to market yourself.
On the contrary, my comment began "To write an effective resume..." Translation: the rest of the comment is going to be advice to my fellow HNers about how to market themselves. I'm not sure how you interpreted "showcase your actual work well and present it in the most impressive possible light" as "just create another project on github".
My point is that this particular resume answers all the wrong questions. All the questions I don't really care about when I'm making a hiring decision. Only at the end does she say "So... What're ya waiting for!?" and link to her portfolio. And her portfolio isn't nearly as well done as all the fluff sections ("I'm vehement about creating kick-ass interactions" and "I never wear high heels"). This is a mistake. The most prominent and polished part of her resume should showcase her actual work. She should answer the question "What have you built?" right away and in impressive fashion. Note that the question isn't "Have you built stuff?"; it's "What have you built?" So, the fact that Stuff Got Built, as you say, isn't very important. I don't care that "clearly, she can build stuff." I care to see what she's built. So, show it to me. In other words "showcase your actual work well and present it in the most impressive possible light."
