I think the set of principles we've been operating under have been working pretty well and I believe Chris to be a genuine person, but I'm biased by being personally involved with this particular story. It might also be important to note that while he didn't give the numbers in the story, we all who voted got to see the numbers before and after (he's never hidden them from us) and the effect the new salaries have on our bottom line.
I can see how it could go wrong given employees trending towards unhappy/defensive and a boss trending towards dishonest, but that would be an awful situation to be in no matter what kind of gimmicks the bosses introduce.
