1. government or the holding of power by people selected on the basis of their ability.
2. a ruling or influential class of educated or skilled people.
"skills" or "ability" don't just mean "technical skills," or "technical ability."
Personally, I find that in many tiny companies you actually see the opposite of "social skills" -- they become so deeply, desperately, dependent on the particular technical genius of one or two people that those people can basically do everything and anything they want to do, because the company doesn't think it could survive without them. I've worked in small startups where one of the three principal engineers was allowed to sexually harass an ex-girlfriend; in the same place, another principal engineer was such an asshole people basically routed around him. And the third one? He was a a perfectly pleasant guy I loved working with.
Getting things done, in most environments, includes working with other people. I'm a big fan of the "no brilliant jerks" rule. See "The No Asshole Rule" book for more discussion of this.
