Kathy Sierra kicks ass.

Yesterday I caught up on some blog reading, so I was going to link to Kathy's excellent posts on the theme "Dignity is Deadly."

But I didn't get to it yesterday, and by the time I got there today I see this compelling new post on "How to be an expert."

Given that I've linked to her stuff before--repeatedly--and that a couple of my friends and I have had long talks about what she's written, I figured it was time to add her to the sidebar here and give her a particular plug.

Do yourself a favor and make a habit of reading Creating Passionate Users.
