The job profile 'Creative Technologist' has become something like the It-job of 2010. I don't know when these thing start, but if you want to be hot in digital nowadays you must be into social media a creative technologist.
I doubt there is a desperate need for an autonomous job profile like this in most digital agencies. But I sense there is one in rather traditional shops. BBH (even far from being a traditional agency) have an attitude on the role of a Creative Technologist. Or to be more precise - BBH's Griffin Farley has presented his vision about the (future) role of a creative technologist.
As usual, great stuff Griffin.
