The web's three leading search companies -- Google, Bing, and Yahoo -- have announced a new collaboration called Schema.org, where more than 100 new types of website markup for content like movies, music, organizations, TV shows, products, places and more will allow search engines to better understand and present what they find on the pages that show up in search results.

This will change the way people design websites, it will change the way people do search marketing, it will change a lot of things. It should be very interesting.
