StructuredBlogging.org - What is Structured Blogging?: "Structured blogging is about making a movie review look different from a calendar entry. On the surface, it's as simple as that - formatting blog entries around their content.
To see what we're talking about, check out the sample content on the blog.
On another level, it's a bit more complicated - what we want to do is create structure (in the form of XML) around each of these types of entries, to organize the data inside and to let machine readers - other programs, sites, and aggregators - better understand the content."
