title: How is the HTML5 cross-browser story going to be any different than CSS/JS?
body: <p>When CSS and JS got popular, the big frustration was that every browser implemented it differently and only a limited set of "cool stuff" worked across browsers, or worked differently.</p>
  
  <p>Now we're making HTML5 popular, so it seems like we're about to embark on the CSS/JS incompatibility journey all over again, but now in a 3D, animated, and video-playing style.</p>
  
  <p>My question is this - are the big browsers varying HTML5 implementations in such a way that we're headed down the same path again? Is there another IE6 around the corner?</p>
  
  <p>If not, what makes this story different?</p>
