Bert Bos: ‘CSS X’ (W3C)
People have argued that there should be new versions with a certain frequency. But not too often, because people don’t have time to read too many announcements. And people will want to write books about the new version, or develop talks and courses about it, which takes time. As Jen Simmons wrote, quoting Chris Coyier, ‘a tremendous number of books, courses, and conferences were dedicated to CSS3’ even though there is no definition of what CSS3 is. The working group certainly never defined it.
