> one of the worst pieces of IE 6's reign of terror: the stagnation.

This is the thing that I think developers today don’t seem to be able to get their head around. There was a fourteen year time period between Internet Explorer 6 being released and when it dropped out of usage worldwide. Even if you only had to support the USA, it was still eleven years. People could go their entire careers without ever knowing what it was like not having to support it. It paralysed front-end development for more than a decade.
