I guess I'm left with two questions after reading this article:
1) If you replaced the word "information architect" and "IA" with
"interface designer" and "UI" would you have the same article? If so,
then why not just use those terms instead of constantly referring to
the job as "IA" throughout the article?
2) I think the author somewhat neglects the issues on who makes the
final decisions in any design. After all, in the business world,
someone has to be accountable and make the final call. The real
question here, how do titles and job function also affect the decision
making process on a project?
If a self-proclaimed IA has no background or training in visual design,
should they make the final call on what icons, typogrpahy and color
systems to use? Would the author mind if a self-proclaimed UX person
told them that the entire taxonomy proposed was simply wrong, when it
seems quite clear that UX person had little background or trianing in
that sort of work?
