Meta Forms
Johnson goes on to talk about a "meta" form of commentary. In the past hundred years, we've moved from the victorian novel of storytelling to the meta discourse of commentary on other mediums. Television about television. Books about books. Commentary about events. As Johnson puts it, "The infosphere is now part of our "real life" - which makes commenting on it as natural as commenting on the weather."
Thus, we have programs like Talk Soup on E! (or, anything on E! as Johnson points out) which give the highlights of talk shows of the week.
This phenominom exists on the Internet as well. We have websites about other websites. We have standards organizations such as the www.w3.org (the world wide web consortium) who dictate web standards for browser companies and developers to code to in order to create a better online experience.
XML is a meta language-that is, a language about how to write languages for the web. It seems like everything is moving towards XML now. The benefit is standardization of form, but what information does it give us?
We're back to decision theory-how do we trust sources? What information do we believe? What do we do about information overload?
