It’s better to say that we’re all in the documentation business. We construct media, not because we’re going to have a conversation *today*, but to have one in the future, if we’re lucky, across many generations, with many readers, Talmudic-style. I would venture a hypothesis that the most successful businesses (and open source projects) have the best documentation, but I do not have full time to test it out.

The document culture operates between us like so:
You write a blog post about Google in 2004, and you expand it to a book in 2005, and I first become aware of it in 2006, and then I write a 3,000-word response to it in 2007 (ok, in December), and, now that it is 2008, perhaps we may talk about it now, such that you can fulfill your promise “I am committed to updating this work at the Searchblog site.”

No rush… Media (in the strict sense of the term) is ephemeral, but documents persist.
