I just encountered this so don’t have any details to report.
But, if they put as much effort into the technical side as they did the marketing images (Your App versus Your App on Precog is particularly funny), then this could prove to be quite useful.
It is in private beta so not much to report. Will update when it comes out of beta or I can point to more resources.
I first saw this at KDNuggets.
