Google previously announced that it would no longer support IE6, yippee!! Now they have gone another step further and have released a statement:
"Beginning August 1, 2011, we'll support the current and previous major releases of Chrome, Firefox, Internet Explorer and Safari on a rolling basis. Each time a new version is released, we’ll begin supporting that version and stop supporting the third-oldest version."
