There’s “Complexifiers”, people who go out of their way to make things more complicated, and there’s “Simplifiers”, who thrive on paring things down to the basics. More from Scott:
Do you make things more complicated? – Rojo – LifeHacker

Complexifiers are averse to reduction. Their instincts are to turn simple assignments into quagmires, and to reject simple ideas until they’re buried (or asphyxiated) in layers of abstraction.

Simplifiers thrive on concision. They look for the 6x=6y in the world, and happily turn it into x=y. They never let their ego get in the way of the short path. When you give them seemingly complicated tasks they simplify, consolidate and re-interpret on instinct, naturally seeking the simplest way to achieve what needs to be done. They find ways to communicate complex ideas in simple terms without losing the idea’s essense or power.

bloggerには逆のことをやっている奴が多いがな。
