I'd prefer to spend most of my time on actual work. I'm getting back into Clojure and rediscovering the joy of coding (which disappeared, with fleeting breaks in it, when I went to Google and had to answer to a middle manager, which just sucks all the life out of what we do). That said, if someone is willing to give me $40,000 to tell him what he's doing wrong, I'll do so.
(In person, I'm much less abrasive, though. If I actually respect someone, and I respect most people, I'm nice.)
Burned Bridges Consulting would work because it's structured to produce the only employment relationship in which telling the truth is possible: one where there is no possibility of continuance.
