Microformats
Microcontent publishing, the postmedia mode of writing in microchunks, which can then be re-used and shared in a variety of ways, require Microformats.
For example, book reviews could be more efficiently collated if there was a uniform way to recognize them through microformats.
"Microformats are embedded into webpages and discovered by search engines like Google or Technorati. Microformats are creating common definitions for "What is a review or event? What are the specific fields in the data structure?" They can also specify what we can do with all this information." (Marc Canter at http://www.alwayson-network.com/comments.php?id=12412_0_1_0_C)
