Here is a page using a lot of current and bleeding edge web technologies. Specifically, HTML, CSS, SVG, MathML, Scripting, DFXP, Ruby, and RDFa. I don't know if anyone will get anything out of looking at it, or the markup, but it's nice to know it's there. Of course, it works in all the modern browsers so no version of IE will display it.
It is a very large topic to talking the future of the web . Maybe web2.0 3.0 and so on . Html markup are going to w3c valid . And server side web languages are developping day by day , open source, secure, reusable . I think it is the trend and future .
