This has stuck in my head since first reading it: So what do you do with all these [feature] requests? Where do you store them? How do you manage them? How do you track all these requests? You don’t. Read them and then throw them away.

Actually I think it’s just a business process implementation of a cognitive reality, namely that if you can disregard some of what you see, you’ll do a better job remembering the visual input you deem important.
