What is a microformat?

There are different microformats for different types of information. This plugin uses the hReview microformat for review type information. For more information, see the main microformats site.

Why would I want to use this?

If your reviews are displayed on your blog using the hReview microformat, it makes it easy for search engines to find and do special things with them. For example, there is a reviews search engine run by Technorati.
