George Wright of the Sydney Morning Herald has written an article examining the content of web pages.

For example, if you were using a program that read this webpage aloud to you it wouldn’t know which part of the page to start reading from. If there was some information within the webpage that told the program to only read this blog post it would be much more efficient at working out what part of the webpage is relevant.
