Absolutely true. I know this becuase my girlfriend just went through a long search for a marketing position relatively similar to this one. Never once did we think of putting the word "hacker" in her title even though she will end up doing a lot of web development work.

The ad might mean something to them, but it really means nothing to the people looking for jobs outside of those that read HN a lot and/or read pg's essays on redefining the term hacker. That is narrowing your search to a section of the echo chamber, which is even worse than the echo chamber.
