Funnily enough, the only time I've been asked a genuine logic puzzle in an interview was at ITA (don't remember the details, but it was something about ants walking on a 1d line and bouncing off each other). It even had some kind of a "either you see it or you don't" aspect as well. But the programming puzzles on the website were just awesome, even though I just solved them because they were fun, not for applying for a job. I've been surprised that nobody else has done the same thing, but your explanation of how much work went into the puzzles kind of explains that :-)
