"300 character are not enough to describe how awesome this stack is. Initially, finding a use case seems far fetched, but once you start you just cant put it down. The ideas start flooding in. The stuff you can do with PI is limitless and on top of that, it works fantastically with the other stacks. What more can you wish for!"
