I'm interrupting my usual stream of geek consciousness to bring you a message from our sponsors. I'm very pleased to announce that the Jetpac iPad app is now available! Some of your friends are taking astonishing travel pictures that you've never seen. Get the app and we'll give you the very best of the two hundred thousand photos your friends have shared on Facebook.

Ratings are very important to help other people discover the app, so if you do enjoy it, please consider taking a few seconds to rate us too.

There's a lot of data stories from this release, and I'll be writing about them over the next few weeks, in between new features and bug-fixes for the next update!
