“Sadly, tools for conceptually laying out sites have remained fairly rudimentary. Sure, you’ve got programs such as Visio, Inspiration, and the very fine OmniGraffle to work with. And yes, all have been extended over the years to incorporate many Web-friendly features as a nod to information architects who use them. But they still seem a bit stilted, more suited to org-chart makers and programmers than creative folks who want to be able to take what’s in their head, play with it a little, then lay it out on the page to guide a development effort. A good IA tool should work like your brain. Is there one? Yes. It’s called Tinderbox.”
