I actually would not want to limit myself to one industry. Working at a digital agency has its short comings but one thing I enjoyed is the variety of clients we get.
For example, I have a mixed skill set of web development and graphics programming. That's allowed me to interview at companies from a variety of business problems that leverage the graphics skill set, such as CAD/CAM, indie video games, or space mission simulation.
I want to say "I solve these problems" without limiting myself to one industry but relying on my tech skill as the niche. Is that just as good?
