I totally disagree. These things are not obvious. I thought it was a great post. My friends have asked me why dropbox and youtube haven't added any new features in years. The business people that I work with do not see and do not understand the subtleties of software. If I tell them adding a map in one part of the software will take 10 minutes, and 10 weeks to add to another part, they don't understand why. When I explain it, they understand why, even if they don't like it. There needs to be a lot more "this is why software development behaves the way it does".
