title: An interactive guide for web page elements?
body: <p><a href="http://tracelytics.github.com/pageguide/" rel="nofollow">pageguide.js</a> shows usage help about web page's elements by overlaying help balloons over the page. The concept is great, but pageguide.js doesn't support IE8, is hard to customize (eg. font sizes), and a little slow. </p>
  
  <p>Is there anything similar, that would work better, especially on IE8?</p>
