Its working this way in Privacy work and Cascading Style Sheets too. But in HTML, the competition runs as far as competing for versions of the standard on which much of Web interoperability, and the warp and weft of most of cyberspace, relies. It's no wonder consumers, buyers and IT managers are concerned. In HTML, things happen differently. Browsers, while supporting the latest standard, also support new features.
Some features die in the market place and are never heard of again.
Others become product differentiators between the cool and the even cooler. The features the market likes are quickly replicated, often in incompatible forms, by other browsers. At this point, engineering teams at each technology provider are saddled with supporting two or sometimes three ways of doing the same thing. Lack of industry consensus is making product clumsy to maintain, and buyer excitement turns to buyer nervousness. It is time for the engineers from each company to sit around the W3C table and hash out a common solution.
