I stumbled across the musings of Andy Edmonds and got stuck for a while. Good information about Mozilla and UI design. I was intrigued by his suggestion of a scripting solution to the problem John Robert Boynton describes:

Google should recognize weblogs as a document and site structure, and link to the archive url, not the main page of the weblog… Thus it would be better to point to the archive. This would require a convention similar to the robots.txt convention. Google is perfectly placed to initiate the convention.
