A little while back I posted about Yelp's inclusion of Monocle; an augmented reality setting in their popular iPhone app.
The release notes in their newest update take a playful look at using the feature. Monocle uses the iPhone's camera to display a person's surroundings overlaid with businesses and their ratings. The copy is a cheeky warning about improper use of the feature. It serves to amuse people who already know about Monocle and intrigue those who don't.
Since the update seems to mostly address issues around the latest iPhone OS update, it's nice to see them using the notes to further the fun and outgoing nature of the brand.
