First off, I apologize that I came across as disrespectful. I was being curt, and it wasn't my intent. I absolutely welcome and encourage differing opinions and appreciate you taking the time to comment! I was confused because your statement seemed contradictory.
Secondly, titles absolutely do matter because words matter. That's the entire point of the article. Sure, roles and responsibilities may vary from place to place, but the design community is capable of and has a responsibility to do a better job defining our tasks and roles. We need to own our identity rather than let others define it.
