Invention entered public domain

Today it is one year since I filed a provisional patent application for the StackHR concept. As I have chosen not to follow that up with a non-provisional patent, the idea has now entered the public domain as of today.
I probably won't be able to find time to make a publishable article on the subject any time soon, and I think the same goes for professor Zhang, who has, however, told me that he will keep it ready in the drawer.
It is my hope that somebody will come across this blog and pick up the idea, and develop it to the point where it can find real world applications.
Now the idea is at least free for anyone to use however they might want.
