Pinterest Advent Calendar Promotes Travel App

A startup that makes Jetpac, a "travel inspiration" app for the iPad, has created an Advent Calendar on Pinterest to tout the app. The Pinterest page counts down the 25 days until Christmas. Each day, one of the 25 most popular places to which Jetpac users traveled to in 2012 is revealed...with generous links to the app. itself, of course.

Pinterest users are asked to pin photos from each day's destination to any of their boards and tag the pin with #JetpacTravel. Each pin enters the person into a contest to win $1,000 worth of travel gear. A winner will be chosen on December 25 at 2PM PST.

Is this a good use of Pinterest? Let us know below in comments.
