I haven't even approached that subject in this thread, so I'm not sure why
you're chiming in here. We're talking only about definitions. I'm very much
interested in reaching a definition to some of these key terms so that we
can stop debating the definitions every week in thread after thread.

Of course, I am also interested in defining UCD so that I can more
effectively make a case for ACD. The differences need to be clear so that
the appropriate solution can be chosen.

Funny - I've designed apps for both situations, so this is a wonderful
example.

The problem is in how you framed the question. You're looking at the
different audiences, so you're seeing differences in audience type. I looked
at the differences in the activities. I designed both to support different
activities.

Instead of constantly harking in a mine-is-better-than-yours format, why

I have written a 3-part article on this subject for Peachpit.com to attempt
to explain more about the approach and how to use it. Pt01 is
up<http://www.peachpit.com/guides/content.aspx?g=webdesign&seqNum=352>and
the others are on their way.

This very short series isn't nearly as comprehensive as I'd like. It may
turn into a book someday. Don't know yet. Don't know if I care enough about
the whole subject yet to write the book.

With all this in mind, I still don't understand why you're calling me on
this in this particular thread. I have yet to say anything about ACD being
better than UCD. I've only said we should work to define both.
