> I am immediately thinking of the horribleness of how some of the (older) javascript frameworks re-invented the back button (and browser history in general) instead of.. ya know, using the browser. They did that because the browser didn't support adding to the history via JavaScript. But even now that the browser does support adding to the history via Javascript ... is that really just "using the browser"? At some level in many modern web apps back button history is not just the browser. This isn't an ancient thing left behind with old frameworks.
