What a job huh? I wonder if my bio/geology background would help land this cool gig? I am scuba certified... Ah hell no, there are millions more qualified.
From what I can gather the successful applicant is expected to be a one (wo)man advertising campaign via a blog. So I guess personality and journalistic skills would be two of the main criteria. Check the official site, but be warned it's extremely slow, guess it's getting a lot of traffic.
