The T-Shape Person

There's a lot of metaphors out there that describe the difference between generalist and specialist. I think Jameson has heard of a few of these and he told me a great one earlier. The T-shaped person is someone who has broad knowledge but goes very deep in one area. Over time, developers tend to be more like capital M-shaped where it's like they're a T. And every once in a while you dive deeply into something so you're specializing in a lot of different things.
