Commentary

In a way that is directly or indirectly appropriate to the number 5, the HTML5 standard makes a mockery of the very idea of a standard by being a "living standard".

On top of this, HTML5 is the Perl of web standards, which is to say, it's like playing Katamari Damacy with the web. From what I can tell, the standardization process goes something like this:

  • Pick a feature, any feature.
  • Does any browser currently support that feature?
    • If so, research how all browsers implement that feature. Codify the upper bound of that behaviour and put it in the spec.
    • If not, would the feature be totally awesome to have anyway?
      • If so, codify that feature and add it to the spec. Don't worry too much if browsers implement it yet or not; someone will write a polyfill anyway. Let browsers use words like "maybe" and "probably" to describe their level of support for the feature.
      • If not, try again.

The number one best thing about HTML5, in my opinion, is the <canvas> element. At long last, I can just draw stuff on a web page, and that's actually really nice.
