In a few years, we (as in web developers) will no longer be speaking the language of (X)HTML4(.01). We will no longer speak the language of <div>'s. No, in a few years, we will no longer be partying like it's 1999. HTML5 (or Web Applications 1.0 as people call it who use the Web 2.0 phrase as well) is on it's way. Since three major Browser vendors (Mozilla, Apple and Opera ) came together as the WhatWG (Web Hypertext Application Technology Working Group) to construct the new HTML standard, the basic thought of the extended HTML version becomes more and more clear. Backwards compatibility width HTML 4.01 and XHMTL 1.1, more specific elements to fulfill the needs of web applications (instead of using <div> for every single one of them), <audio> and <video> tag support, the <dialog> element to describe conversations and many more functionalities. Sounds promising, isn't it?

To give you a impression of what the new HTML standard will look like, I've composed a top 5 resources for further reading:
