Never mind IE11. <a href="http://motherfuckingwebsite.com" rel="nofollow">http://motherfuckingwebsite.com</a> still works on IE6, and why shouldn't it? It's plain HTML with no CSS or JS.<p>There is no reason why any web document should not still be readable in Lynx, Mosaic, or even WorldWideWeb.<p>Web applications are a bit more complicated, but that complication is self-inflicted. We developers choose to to hijack users' devices for work that should be done on the server in the name of providing a better user experience, and we make our work harder in the process.<p>Supporting old browsers isn't that hard. Build a solid foundation of HTML, HTTP GET, and HTTP POST, even if it means doing full page refreshes. You can always layer your AJAX calls and such on top. It's called "progressive enhancement", remember?
