When you want to build something for the web, it's surprisingly difficult to find out how you can implement your vision across all browsers and operating systems. You often need to search across various websites and blogs to learn how certain technologies can be used. It's kind of like a scavenger hunt, except it's not any fun.
This scavenger hunt is soon coming to an end. Google along with the W3C and several leading internet and technology companies just announced the alpha release of Web Platform Docs. Web Platform Docs is a community-driven site that aims to become the comprehensive and authoritative source for web developer documentation.
