That page looks like a teaser. I tend to suspect that the "supermodels" are popping up for the same reason that, when you look at those T-shirt ads on the edges of blogs, every T-shirt is being worn by... a supermodel. In practice, I presume they offer to try to screen for people who actually want to be hired, not just the ones with big scores on Githubbiness. I note that the very first thing they tell you to do on the "Job Seekers" page is to set your "hireable" flag on Github to true. (I didn't yet realize Github had such a thing, BTW. Thanks to GitHire for teaching me that, if nothing else.)
