These guys are going to make a real splash! I went to EDC in Vegas this year and used an App just like this. Kind of a hassle though because I had to DL it to my phone and then delete it later. Web apps would have made a lot more sense. I was also able to make an app (a beautiful one by the way) in about 5 minutes! I had some fun exploring the possibilities beyond those 5 minutes, though ;-)
