The specs are quite long and I'm starting to have a glance at them, so for the moment I'll just publish some links while I'll write the first impressions as I finish reading them.
Some of the most interesting new features for authors are APIs for drawing two-dimensional graphics, embedding and controlling audio and video content, maintaining persistent client-side data storage, and for enabling users to edit documents and parts of documents interactively. Other features make it easier to represent familiar page elements, including <section> <footer>; <nav> (for navigation), and <figure> (for assigning a caption to a photo or other embedded content). Authors write HTML 5 using either a "classic" HTML syntax or an XML syntax, according to application demands.
The HTML 5 specification helps to improve interoperability and reduce software costs by giving precise rules not only about how to handle all correct HTML documents but also how to recover from errors.
