Summary: About tagging Channel 9 content, as a way of grouping similar information

RelTag is one of several MicroFormats By adding rel="tag" to a hyperlink, a page indicates that the destination of that hyperlink is an author-designated "tag" (or keyword/subject) of the current page. Note that a tag may just refer to a major portion of the current page (i.e. a blog post). e.g. by placing this link on a page,

		  <a href="http://technorati.com/tag/tech" rel="tag">tech</a> 
	

the author indicates that the page has the tag "tech".

The linked page SHOULD exist, and it is the linked page, rather than the link text that defines the tag.
