Has Anyone Used the NASA App Store?

Has anyone checked out the NASA App Store and wants to share their experience? Caught an article on Government Technology and was wondering if anyone has been in the app store - seems like a really cool way to connect employees, especially in such an enormous organization like NASA, with field offices across the country. I'm curious of what some of the features are internally and what kind of collaboration can take place.

I also wonder if this is something that can be replicated by other agencies - or if the nature of NASA's work makes an app store work best.

Be interested to hear your thoughts..
