Great to see I'm not alone with this crazy idea. When writing the previous comment I actually started thinking if I would pay someone to actively look for the best job I can get at any given moment, and that I would probably pay for that happily. Of course, you make a serious point about considering that same payment after X years in a stable job (e.g. I've been with Google for the past 3 years... I'm not planning on changing jobs.. why should I pay this guy every year?) very interesting things to ponder over.
Again, thanks for sharing!
