If you look at the bottom right-hand corner of the screen, you will see a Flash movie that contains tags that have been automatically generated from the content on this page. You will find one on every page of the blog.
Click on a tag, and you will see a number of areas related to the tag you have clicked on. You can keep on following these on (which can be quite fun), or instead use the search buttons at the bottom, to search this site, Google, Wikipedia or Amazon.
This is a generic implementation of our tagging engine, which can be configured for specific applications.
Look out for tags in brackets - this is the first implementation of our “Theme” engine, where we assess the underlying theme behind a document.
