What is a "True" Interaction Designer?

I just finished reading Uday Gajendar's blog post about What’s a “true” interaction designer? I find little to disagree with. I have always been partial to (and perhaps over-emphasize) the aesthetic and graphic aspect of my job, but I wouldn't expect someone to say that it isn't part of my job.

But it is only part of the job. There is a lot to it. His bullet points are worth noting:

• Believes in the human experience...
• Is a champion of aesthetic value...
• Leads with a design process...
• Does typical process artifacts like diagrams, flows, wireframes, site maps, system models...
• Sketches, draws, visualizes, iterates, prototypes, over and over again, to get better resolution of solutions for well-defined problems.
• Takes pride in the craft of making a superb experience...
• Leverages research (of users, of technology, of business)...

I particularly liked how he wrapped up the discussion, though. "In sum, my view of a “true” interaction designer is really an informed visionary."
