Recently there has been a big bruhaha in the IA/UX world over Joshua Porter’s post declaring that information architecture is dead. If you haven't read it yet, it's a great way to get the blood pumping first thing in the morning.
I read the post and just sighed and shook my head. Folks just don't get it. IA doesn't have to be put in a box. It's more than just "make my web go better" (as Peterme likes to say) - physical IA, mobile, etc.
But the "make the web go better" is still valid. There are a lot of interesting, important web-based problems that are still out there. I wonder how much of our 30-second sound bite culture is behind this obsession with "solving" something and immediately moving on?
