Another clever use of social media by Crispin Porter + Bogusky for Kraft Macaroni & Cheese, Smile Tagging is a Facebook app which allows you to to show love for content you like on the Internet by tagging it with your real smile.

Tying in with the product's You Know You Love It positioning, it's also first app which allows you to tag content with a photo, rather than just a 'like'. The Kraft Macaroni & Cheese Facebook page will feature a gallery of faces, which you can click on to see the content they recommend.
