A Pay Cut for Personal Growth?

As as follow-up to an Ask Slashdot from earlier this week hatch815 asks: "I have recently been extended an offer to come work as an engineer for one of the internet search companies. In responsibility, this will be a step back, as I am currently in a management role, but as a career direction, it will provide me with unlimited exposure, learning, and advancement. The place where I work now is a small non-IT centric shop. Although I am management, I am at the top of the ladder. The tough decision is the pay decrease I would take if I did take this new position. Is the prestige and exposure worth giving up responsibility? I am too stuck in the big fish small pond mentality? Is going back to the forefront better than the psuedo-management I do now?"
