I can't stand the "blog post as conversation" format. It's fine if you're quoting a conversation for one or two paragraphs, but for something this long you should do me (the reader) the courtesy of speaking directly to me. Also this is giving way too much credit for the creation of the URL. The format of the URL is not some miracle, genius insight. It is a natural result of network computing, and similar descriptors…
This is an example of a Socratic Dialog[1], and relies on metaphor. It's in that way a piece of art useful as a teaching tool, but as such it trades some precision for the end effect. 1. http://en.wikipedia.org/wiki/Socratic_dialogue
I think something would have to be done with a bit more art and skill before I would consider it Socratic dialogue. This is just a clumsy blog post that is annoying to read, IMHO.
