Microformats are the dark-horse of the web 2.0 race. They are going to be the left overs of a time that brings a lot of great features, automation, and rich applications. In a series of articles published by Alex Faaborg, he discusses microformats.

The combination of blogging and microformats is now reversing this model. Now, your information remains in your blog, and the Web sites come to you. For instance, if you want to sell something, you can blog about it using an hListing, and a site like edgeio will find it when it aggregates classified advertisements across the Web. Similarly, the microformat hReview allows the creation of review aggregation sites, and XFN (XHTML Friends Network) allows the creation of social network aggregation sites.
