Hey Luke, thanks for posting this, I'm a big fan of Exposure too.
I've been doing travel apps for a while, I also did Tripovore (http://tripovore.com) that I never really launched. I launched Somewhere a while ago and it has been a great experience so far, but I don't have time to work on it anymore. I'm glad people are still enjoying it though.
