I read a provocative rant about "Lame excuses for not being a Web professional" on 456 Berea Street that got me thinking about the nature of being a usability professional. A couple of years ago, it was rare to see any job postings in the field that required more than relevant experience. It's become much more common now to see open positions requiring specific degrees in human-computer interaction, human factors, and interaction design.
I'm cheering on this trend because it fits the domain so well. Good usability is all about applying consistent, well-thought-out methodologies, and also keeping current in cutting-edge technologies. You can't rest on your laurels because there's so much to learn and so many problems waiting to be solved. Challenge yourself and don't settle for inconsistent visuals, substandard accessibility, and excluding potential users.
