Throughout my career, I have quite often heard this question being asked "What's the difference between a manager and a leader"

I know he shelters us from storms from the world above where necessary and also brings us into discussions where appropriate.

He has also started up a secondary blog that looks into getting leaner and greener with IT. I recommend the read: Dynamic Work
