HTML is a standard dictated by browser vendors – not an independent body.
That seems to be the message from the Web Hypertext Application Technology Working Group (WHATWG), which has announced it would be dropping version numbering from the HTML specification once work on HTML5 is complete. Henceforth, HTML will become a "living standard," with the most current version of the specification being the one maintained on the group's website. In other words, the standard is whatever WHATWG says it is this week.
Technically anyone can participate in the HTML standardisation process, via WHATWG's mailing list. But those who do so are known as "contributors," and their role is much like that of concerned citizens at a city council meeting. Actual membership in the WHATWG is an elite affair, however, and is by invitation only. Currently the total membership consists of three representatives from the Mozilla Foundation, two from Opera Software, two from Apple, one from Google, and one independent developer.
In effect, that is who is deciding the future of the web: four of the leading web browser vendors, all of whom have incentive to pile ever more features into their products to compete with alternative RIA (rich Internet application) platforms such as Adobe Flash and Microsoft Silverlight. (If you're wondering where Internet Explorer fits into all this, notice that Microsoft is not a WHATWG member.) What is more, Apple and Google are both prominent providers of web content. But hey – surely they all have our best interests at heart, right?
