Boss, just add the st_via="[@theathere]" attribute to the span
<span id='twitter' class='twitter' st_via='[@theathere]'></span>
<script type='text/javascript'>
var defaults = {
"service": "twitter",
"element": …,
… etc,
}
stWidget.addEntry(defaults);
</script>
it will automatically add the st_via='' try it.
