Structured Blogging allows bloggers to easily add structured meta-data to blog posts, such as movie reviews or event listings, so they can be easily found, read and syndicated by other sites.

The ad-hoc XML (no standards body has yet decided on what elements should be in such data) would make possible a search for book or product reviews that only returned real reviews, instead of the current jumbled listing of commerce sites and spammers that search engines currently provide.
