The one purpose in our existence that seems incontrovertible is that we should work steadily to improve the quality of the lives of our children and children's children. IE6 had a difficult, highly criticized life and kept mostly to himself, but he was also successful in this one respect.
Transparency was incredibly difficult for him, perhaps because it would expose too much of his pain. But by forging his way in a world where there were no standards (at least that he was aware of), he did the hard work for his progeny, and IE6, 7 and 8 are a testament that from the flawed can emerge a greater perfection (though there's still room for improvement). And for all his backwards ways, IE6 is still valued by holdouts across the world who rally for the qualities that he was unable to pass successfully onto the next generation. IE6, I salute you and respect your role in my world.
But damn, good riddance.
