I have been following this thread with interest. Since the
pro-interactive and anti-interactive arguments have been reasonably well
presented, I have stayed out of the conversation. However,...

I think that would be the wrong conclusion to draw from the debate about
interactivity.

I agree with this wholeheartedly.
