Maybe my comment was not written clearly enough. I am not saying that what is described in the article as BS managers are good, effective managers. They are not -- two things: required long hours and not taking responsibilities are killer signs.

My point was that the classification into S-W, etc. is simplistic and does not distinguish between good managers and poor ones. Good managers exhibit some of the same traits (delegating, surrounding themselves with smart people, etc.).

On stealing credit: can you elaborate what you mean by that. In my book, a good manager should advertise his best contributors to his management in exceptional cases. But most of the time, the manager himself should receive credit from his superiors on his team progress and request goodies (raises, bonuses, etc.) for his team in return.
