I think that as it's currently practiced and I base most of this on my involvement in the same community that you described, information architecture is a pretty large field. There are far more people doing maybe what you would call hard IAA now or at least more speaking about it. And there's a mix of designers and data modelers or however you want to think about that side. So I think that the field encompasses that entire range of practice. Some people work in the middle where they do both kinds of things. It took me a little while to come to grips with this sort of idea because I don't do interface design or anything like that. But I think my perspective has changed.
