It basically shows our proof-of-concept. I agree it hasn't a strong usecase. You create and move rectangles, change text inside those, and everything is instantly seen by others who have opened it (or on your second tab/browser).

Right now, we're trying to attract developers for building their own apps with their own specific usecase.

By the way, thanks :D

It feels a bit like Google Wave but for use in your own application.

However, I have no idea if I'm right.
