What I said. What Seth said. The best part of his post was:
"Great design is intuitive. Great design eliminates confusion. But not for everyone, not all the time. The words and interactions you use often have a sophistication that will confuse some portion of your audience.
Why not consider making it easy for the confused to ask for help? And treat them with respect when they do. If you don't create a little confusion, it's unlikely you've built something remarkable.
And to go one step further: sometimes it's okay to lose the n00bs. Not in an arrogant way (except for some brands) but in a way that says, "this might just not be for you..."
What Chris said was in his book, the Long Tail. What Seth said regarding that.
Good stuff, all around.
