Part of what can be annoying about the "rock star" label -- other than that it's a buzzword -- is that it's now a buzzword without a standard definition. At one point it clearly meant "you, o techie, are a recognizable name and thus a brand unto yourself." But in the last few years it's come to mean "miracle worker."

I got so worked up about this, some weeks ago, that I even blogged about it: http://advice.cio.com/esther_schindler/rockstar
