Microformats define ways to make your markup more descriptive, allowing a reader (be it machine or human) to very easily grok the just what you’re getting at. Basically, you know what you’re doing: why don’t you just tell us instead of making us guess?
A simple example: Your link to ajaxian from your blog (you do have one, right?) could indicate that the page you’re linking to should have the tag “ajax”. By adding that tag it’s obvious what you’re linking to and why you’re linking to it.
<a href="http://www.ajaxian.com" rel="tag">ajax</a>
On my blog I may link to ajaxian a bit differently, but due to the tagging someone would be able to quickly determine that my motivation is a bit different.
<a href="http://www.ajaxian.com" rel="tag">web 2.0</a>
The most obvious implication is making SEO-type tasks a bit simpler. A spider crawling your site can be told quite specifically what topics you are truly covering. At the moment you may not see a profound effect from properly applying these tags, but as microformat becomes more and more prolific (and consistent), they will likely be leveraged more and more for this purpose.
