Generalist versus specialist? How about a misshapen comb
This is an expanded view of the T-shaped skills explained in Cammy Bean's "Accidental Instructional Designer." It's not a binary of generalist vs. specialist. Many of us have T-shaped skills; we have a broad base (the top of the T) with one set of deeper skills (the vertical in the T). If you have several deeper skills, a map of your skills looks more like a misshapen, uneven comb.
