This is a brilliant subject for a series of articles. Good luck with the transition.

I'm a techy, but was recently given the opportunity to attend a 2-day course about project management. It was a real eye-opener and has altered my perceptions about managers and the work they do. It also helped me with my own day-to-day work. Anyway, the point being, that too often techy people think they are the only ones that know anything. And, clearly, that's as far from the truth as the oft-repeated mantra that all managers are bad.
