I still don't get why so many people are use Internet Explorer. All the other web browsers are better! I know you agree since 2 third of my visitors use Firefox and 20% use Safari.
Yet Google decided that people aren't tech-savvy enough to decide what's better for them. Therefore they found out a way to let developers decide what web browser to use, or more precisely developers can make people under IE use Chrome. This is the point of Google Chrome frame, an plug in for IE.
