To be honest, both "User Experience Designer" and "Information Architect," especially the latter, have a ring of bullshit, but they are at least in common enough use that I know approximately what the job actually entails (again less so with information architect).

So when you make the change to "Experience Architect," dropping the "User" prefix, it becomes vague to the point where I literally had no idea what you did for living, although I guessed from the article's content that you worked in UX somehow, presumably designing user interfaces or consulting about them. But as someone who (rightly) rails against vagueness in marketing and against bullshit that masquerades as expertise, I would think you'd be averse to a title which trades clarity for puffery.
