There is nothing stopping other browsers from implementing the same features, most of them are probably fully documented standards anyway, even if there was no documentation people could just look at Chromium's source code, which was certainly not the case with IE.<p>This article is immensely ignorant, it basically states that no browser should have capabilities that other browsers lack, if that would be the case than we would end up in a deadlock, because everyone would wait for everyone.<p>Emerging standards need to be tried in the open, Google is doing the right thing, they are trying SPDY with real world web apps and real world customers so that it will mature by the time other browsers implement it and we won't be stuck with implementations that suck.
