What Ben is getting at is that a truly good designer is a person who has little aversion to what medium they're working on. Additionally, I think he's also coded in a bit of a slant toward most of the businesses out there that are hiring who only associate design with certain products or languages. An honest mistake, sure, especially for those who don't know about design.<p>But we're beginning to enter an era where if you run a business and your adement about having a well-designed product, then you should be willing to take the time to develop a cursory knowledge of the industry. Be able to differentiate between buzzwords and the all-too-familiar "insert development platform here" designer. Although his argument is a bit understated, Ben's point is clear: don't waste time with people who aren't absolutely head-over-heels about design. They cost more and sometimes require more resources, but the return on that investment will surprise most people. Even if they don't believe it, people respond to good design.
