"Have you ever tried an application that looked great at first, but once you started using it, it just didn't feel right? The UI was slick and the feature list looked perfect, but the workflow just wasn't there? I see this all the time, and quite often it's due to developers not using their own applications. They built something they thought would sell instead of something they needed, so they don't see their software the way an end user would. They don't notice the hundreds of little things that would make their applications easier to use, nor do they notice all the minor bugs that customers consider too small to report."
