Lots of companies advertise their job openings to the ends of the earth, which we can't really fault in this economy. But rather than let HR weed out applicants arbitrarily, Flickr decided to hide a link to its job postings for coders somewhere only worthy coding applicants would ever find it—inside the source code of its website. Of course, the effect is kind of ruined by other websites posting about it with screenshots of the message, but such is the price of good ideas. Just ask the guys who did practically the same thing three years ago with ads for EA's Dante's Inferno. Via The Denver Egotist.
