A note on the versionless HTML
Yesterday WhatWG announced to drop the versioning of HTML. HTML is to be a living standard. This comes at a very inconvenient time I fear. Over the past few years web standards have, albeit slowly, developed into some mature state: Most browsers support the current (x)HTML, CSS and JS standards to the letter and can do more. However, due to the fact that these standards have evolved so slowly new developments are not included in these standards. HTML5 (W3C and WhatWG) solves a lot of these problems, including features like <canvas> and <video>.
