technorati tag

The technorati tag list is at technorati.com/tag.

A tag can be thought of as a simple category name. Bloggers categorize their posts, photos, and links with any tag that makes sense. They may link to any tag page with rel="tag", e.g. <a rel="tag" href=""> and it will automatically be added to the common list of tags if the blog ises bookmark services like Delicious.com or Furl.com as explained here.

Linking to the politics tag for instance, requires a line like this in HTML:

categories: <a rel="tag" href="http://www.technorati.com/tag/Politics">politics</a>
