The DOM around the vote-radios and buttons changed recently, you'll need to update the JS to make it work again.

<script>
//<!--
( function (){
    var button = document.getElementsByClassName('voteit')[0].firstChi
+ld;
    var votes  = document.getElementsByClassName('reputation');
    for ( i in votes ) { 
        el= votes[i];  
        if ( el.id == "" ) {
             el.appendChild( button.cloneNode() )  
        }
    }
  })()
// -->
</script>

This nodelet hack is very handy trying to vote on longer (sub)threads - especially when visiting with a mobile browser°. No need to scroll to the button now.

°) with a desktop browser you can still type RETURN to submit the form.
