pinterest sorcery
<p>maybe it's some kind of default behavior that I'm ignoring,
but at the moment I haven't the slightest idea of how once you click an element on the homepage of <a href="http://pinterest.com" rel="nofollow">http://pinterest.com</a> the url actually changes ie: <a href="http://pinterest.com/pin/60165344991931565/" rel="nofollow">http://pinterest.com/pin/60165344991931565/</a> </p>

<p>At the same time the page is not changed!
It just loads ajax content and injects the result inside the html. </p>

<p>I never saw a behavior such as this. I'm using latest Chrome.</p>
