I suspect that with the change to the href, none of the data-* attributes, nor the JavaScript snippet at the bottom, are required any longer. We could also style the button using Bootstrap's btn class (and, perhaps, btn-primary, although that's looking pretty ugly at the moment with DDDEA green), and use the nice Font Awesome Twitter icon.

I haven't seen any of this running live, though, I'm just eyeballing HTML, so take it all with a pinch of salt :grin:
