As it seems to be a common pattern with me in recent times, this post has been long in the making and even longer in the thinking. And I'm not done yet, really, but since the 10th IA Summit in Memphis, Tennessee, seems to have expanded our horizons in novelty ways, I have a feeling the times are ripe for a first attempt at my tuppence on the subject. What subject? IA, IxD, UX, and where we stand, of course. And thanks to JJG.
