Terrible share drop-down example

gistfile1.js

// This... stores the current href. Pretty amazing.
var lastHREF = location.href;

// This is the dirtiest way to build the HTML of the share drop-down ever
function getShareHTML(url,title) {
	var niceURL = escape(url);
	var niceTitle = escape(title);
	return '<li id="global-nav-share-facebook"><iframe src="http://www.facebook.com/plugins/like.php?href=' + niceURL + '&amp;layout=button_count&amp;show_faces=true&amp;width=90&amp;action=like&amp;colorscheme=light&amp;height=21" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:90px; height:21px;" allowTransparency="true"></iframe></li>' +
