Introducing Google Doctype

      Pilgrim, Google Code TeamThe open web is the web built on
      open standards: HTML, JavaScript, CSS, and more. The open web is a beautiful soup of barely
      compatible clients and servers. It comprises billions of pages, millions of users, and
      thousands of browser-based applications. You can access the open web with open source and
      proprietary browsers, on open source and proprietary operating systems, on open source and
      proprietary hardware.
Google has built its business here, on the open
      web, and we want to help you build here too. To that end, we are happy to announce the
      formation of an encyclopedia for web developers, by web developers: 
Google Doctype.
In
      its current (beta) form, Google Doctype contains dozens of articles written by top Googlers on
      topics important to all web developers: security, performance, caching, DOM manipulation, CSS
      styling, and more. It contains over 8,000 lines of JavaScript code: Google's own battle-tested
      JavaScript library, released today under a liberal open source license. And it contains the
      beginnings of a test-driven reference of the open web: a reference of every element, every
      attribute, every DOM method, every CSS property, all backed up by test cases.
Well, not quite 
every property; at least, not yet. We're
      still working on filling in a few of the details about the world's largest development
      platform ever, and we need your help. And so we humbly offer this fledgling encyclopedia under
      a Creative Commons Attribution license, and we invite the web developers of the world to
      contribute to it. Sign in with your Google account and 
edit any page, any article,
      anywhere. Create new ones, update old ones, and help expand the world's
      understanding of the open web.
