"10 years ago abrowser was born.

Its name was Internet Explorer 6. Now that we’re in 2011, in an era of modern web
standards, it’s time to say goodbye.

This website is dedicated to watching Internet Explorer 6 usage drop to less
than 1% worldwide, so more websites can choose to drop support for
Internet Explorer 6, saving hours of work for web developers."
