ClickZ: Qualified Answers to Persuasive Architecture

I have tremendous respect for information architecture (IA) as a discipline and as a profession. But I'm going to ask information architects to take the bulk of the blame for the lack of persuasive architecture on commercial sites. The breakdown occurs in the "sensible business approach" part of the exercise.

Businesspeople involved in creating a commercial Web site don't know, don't value, and are not trained in IA. Information architects must know the value of thoroughly understanding a prospect's buying process.
