Foci of User Experience - comments please

Hi IxD folks, some of you (Dave) may have seen the latest "defining IA"
thread on the IAI list and without wanting to encourage the kind of chaos
that erupted there i'd love to reach out to get your perspective on
something I created to try and distinguish disciplines from roles within UX.

There are a few comments/discussions on it on the post so feel free to junk
that up rather than your forum!
