Jason is running a long comment-thread at his blog about what a seamless user experience might be. What’s seamless, he asks… The answers are pretty predictable, and mostly correct.

The thing is, seams are important.

Try throwing a baseball or a football without seams.

Wear clothes without seams and you look like you’re on Star Trek.

Seams make it possible to get a grip.

The goal, it seems to me, is not to create things that are seamless. It’s to put the seams in places where they are actually useful.
