The Difference Between a UX Designer and Interaction Designer

UX designer encompasses stuff that comes prior to interaction design. Interaction designers are really focused on user problems, while UXers think about a bigger picture. To me, there is a difference, but what matters is does the person you're talking to understand that difference? We can argue, or ascertain right here, there's a difference. But in the end, if you can't communicate what your output is ... then it doesn't really matter.
