What I want to try to do is tell a quick story about a 404 page and a lesson that was learned as a result of it. But to start it probably helps to have an understanding of what a 404 page actually is. The 404 page is that. It's that broken experience on the Web. It's effectively the default page when you ask a website for something and it can't find it. And it serves you the 404 page. It's inherently a feeling of being broken when you go through it. And I just want you to think a little bit about, remember for yourself, it's annoying when you hit this thing. Because it's the feeling of a broken relationship. But these things are everywhere. They're on sites big, they're on sites small. This is a global experience. What a 404 page tells you is that you fell through the cracks. And that's not a good experience when you're used to experiences like this. You can get on your Kinect and you can have unicorns dancing and rainbows spraying out of your mobile phone. A 404 page is not what you're looking for. You get that, and it's like a slap in the face.
