I just retired from a job at a medium size media company. In 3.5 years' time, I went from originally being hired as an interaction designer (really a UI designer) to a UX designer. Without intentionally being a UX evangelist, I managed to convince two product teams to consider the user experience while planning features, to include research, to include me in product strategy meetings, and to think about accessibility from the get go. See my story here: https://medium.com/user-experience-design-1/how-i-became-a-ux-evangelist-by-accident-48298f9b1838

When they advertised for my "backfill", I suggested how to craft the job ad to focus on UX. They indeed hired someone whose focus is UX, not visual design. My work there was done, LOL.

If I can evangelize for UX, surely someone as well-known as Jared could do so, too. ;-)
