Net-a-Porter is an online shop for designer fashion. At www.net-a-porter.com/live, fashion addicts are now able to stalk others of their ilk in real time. Shopping bags on a world map show which products are being bought where at any one moment, together with a photo of the product. Click on the image and a pop-up with info appears, which can also be used to make a purchase. Naturally, users can also pass their discoveries on to friends via Facebook and Twitter.

Andy Sandoz: “A site should have a pulse, and if possible an eCommerce feedback loop.”
