Dear Internet Explorer 6.0 (IE6) Users,
Only 20% of browsers in the world are still using IE6, and 22% of visitors to this site are still using IE6. IE6 is the work of the evil @basementcat. I strongly suggest you upgrade to Internet Explorer 7 or 8.
Why? Later browsers support more web sites, especially the many that are now written with Web Standards in mind. Sites designed with Web Standards render quicker as browsers do not have to magically interpret bad code.
Also, security. As Microsoft takes Internet security seriously, there are strong features in Internet Explorer 8 to stop nasty things happening.
