Probably the most interesting part of this article (and the linked article on developing a URL structure for broadcast radio) is the argument in favor of not making human-readable URLs. A part of me really likes the idea of URLs which can be read and understood by a layman without deep understanding of the system. But technically that's challenging to maintain, and as the article points out, challenging to keep consistent automatically. And arguably it's better to offer users something which you know won't ever break than something more convenient which quite likely will.
