Microsoft officially hates WebGL. They say the HTML5-supported graphics technology, which allows for 3D graphics in browsers without the need for special plugins, overexposes computer hardware to potential attacks on the internet.
As such, future Microsoft products (such as Internet Explorer), won't support the technology. This bummed me out for a second, because I value non-flash 3D gaming in web browsers over a secure computing experience. Then I remembered that I haven't used Internet Explorer since about 2003 and turned that frown upside down. [TechNet via Slashdot]
