[Plugin: Simple Twitter Connect] possible to use async script because twitter is slowing my si

My site is being slowed down by twitter loading up from the header.

If it is possible to use an async script, how would I be able to implement this in your plugin?

<script type=”text/javascript”>
//async script, twitter button fashiolista.com style
(function() {
var s = document.createElement(‘SCRIPT’);
var c = document.getElementsByTagName(‘script’)[0];
s.type = ‘text/javascript’;
s.async = true;
s.src = ‘https://platform.twitter.com/widgets.js&#8217;;
c.parentNode.insertBefore(s, c);
})();
</script>
