One of the coolest things about Internet Explorer 9 (free download here!) is certainly the integration into Windows 7. And site pinning is the feature that pops to the top for most users.

If you haven’t seen it, site pinning is the ability to make your favorite sites just one click away by dragging their tab or address bar favicon to your Windows 7 taskbar. As we’ve highlighted in other past blog posts, once pinned a site can show off more features like custom jump lists and taskbar notifications.

What this really means is anyone can build a Windows 7 taskbar to match their passion on the web!

To celebrate you great site pinners out there, and to show more people the magic of site pinning, we’re holding a little sweepstakes on our Facebook fan page – Pin it. Win it!
