From the current Tumblr preferences page. If you’re a web developer, those italicized words should be music to your ears.

The web, by virtue of free and open standards, is one of the few examples in modern history of an empowering technology that is both universal and egalitarian. But Microsoft, by ignoring or subverting these open standards, has been deliberately clouding the web’s future since the moment their browser gained majority share, because they’re afraid it will ruin their business of selling shit word processors.

Daring Fireball has a very specific policy in this regard: “IE users can suck it.” This is pure idealism, I know, but wouldn’t it be great if every website had Gruber’s balls? Well, maybe we can put that egalitarianism to use and sort of come close.

“Not supported in Internet Explorer.” If you’re a web developer and you can do so without compromising your clients’ interests, you should try to use some version of this phrase on every site you build. I’m not asking you to close off your entire site to IE users. But if you can, include something pretty and/or useful that conforms to web standards yet doesn’t work in IE—you won’t have to try hard—and make it known. Make users who have chosen IE regret their choice and look for something better. You’ll save development time, add years to your life, and help keep the web in the hands of the people.

Not supported in Internet Explorer. Make it your mantra. Because it’s the only way anything will change.
