It's irrelevant? Having everyone access to the engine's base and being able to build upon it, improve it, independent from any one company is irrelevant to you?
Yeah, please. You clearly don't know what you are talking about nor you have an idea of how open source works.
It matters because Microsoft can follow W3C standards now and when it gets 80% of marketshare again they can do the same thing they did with IE6 and nobody can do anything about it. You don't see how that's a possibility?
With webkit that can't happen because it is now owned, nor developed exclusively by a single company. How can you people not get that.
The reason IE is a slower lifecycle is MS supports its corporate apps with such longevity so they can regain their investments. When you spend 10 million dollars to implement a new ERP system, you can give a rats ass about the latest and greatest CSS gimmick, what you want is a browser that works and the best thing to make sure that it works and is supported perpetually is that it adheres to the standards approved by the standardization body. Being able to modify the engine/change things and hack for the sake of hacking does NOTHING to improve the industry, in fact it greatly detracts from the ability to build manageable apps.
also, you seem to like the sound of your own voice. Maybe if you scream it enough people will believe it? lol
