If there has ever been proof that we are living in the end times, it's this: Internet Explorer 8 has passed the Acid2 test. This is the scariest thing I've heard all year.
Interestingly enough, IE8 only passes this test in 'Standards Mode.' From what I've gathered through brief searching around the web, this appears to be an IE8-only feature that requires some 'magic meta-tag' to enable, though I'm only getting the sketchiest details. The comments in this post shed a little light, but not as much as I might have hoped for.
