Is HTML 5 already outmoded?
The latest political football between technology platform vendors that were already skirmishing with one another anyway, is HTML 5, the forthcoming standard for the layout and presentation of Web resources and the framing of interactive content. The way the World-Wide Web Consortium had planned it, HTML 5 would incorporate a number of new standards for audio, video, and interactivity, such that browser makers could incorporate those standards freely without anyone sneaking up from behind and charging royalties.
Telling the major vendors and W3C members to behave and to not seek platform supremacy over one another, is a bit like telling all the rhinestone-speckled characters from some 1970s championship wrestling show to sit down together in a nice circle, legs folded, backs straight, and stop throwing chairs. When W3C itself projects 2022 (no, that's not a typo) as the earliest date that a final HTML 5 specification can be completed and published, some are actually saying that date is optimistic.
