For the last half-day, I've been struggling to produce a new invitation for our big event, the Houston Summit for the Creative Economy. And now that it's finished, it looks like it should have taken 15 minutes. You can see right away that my goal is not to create something polished, but something hard-working that will survive tough environments, like the Blackberry. Information architecture design is like that. When it works, it looks too easy. Not that I think I've mastered it, but I work at it.
