Free the web: boycott IE6

free the web says:

Internet Explorer 6 is holding back the future. IE6 is the bane of every web developer's life. Released in 2001, IE6 fails to even properly support the CSS 1.0 standard from 1996. Supporting IE6 prevents us from using cool new features, standard with up to date browsers. This erodes user-experience for everyone. Additionally, the hacks and workarounds that web designers are forced to use degrades their code, and this limits progress in other areas. Above all it's simply a waste of millions of hours of human potential.

IE7 is better, but still a problem. Encourage people to get a better browser, of which there are several: Firefox, Opera, Safari, and Google Chrome, for example. Or better still, encourage them to switch from Windows to Ubuntu. :-)
