about html (1 Viewer)

The web is constantly evolving. New and innovative websites are being created every day, pushing the boundaries of HTML in every direction. HTML 4 has been around for nearly a decade now, and publishers seeking new techniques to provide enhanced functionality are being held back by the constraints of the language and browsers.
To give authors more flexibility and interoperability, and enable more interactive and exciting websites and applications, HTML 5 introduces and enhances a wide range of features including form controls, APIs, multimedia, structure, and semantics.

I'm sure it will eventually make its way onto the market in some form or other, but I can't really see the point of it - what does it offer that isn't already adequately covered by any number of existing solutions?
