指望着 html5，前端刚有点太平日子可以过，WHATWG 和 W3C 又分出 2 个标准。搞前端的都太悲催了。

Implementations and specifications have to do a delicate dance together. You don’t want implementations to happen before the specification is finished, because people start depending on the details of implementations and that constrains the specification. However, you also don’t want the specification to be finished before there are implementations and author experience with those implementations, because you need the feedback. There is unavoidable tension here, but we just have to muddle on through.
