GPL? That doesn't encourage too many uses of this code.
Especially for commercial purposes.
There are some guidelines here: http://ycombinator.com/newsguidelines.html
In particular: Please avoid introducing classic flamewar topics unless you have something genuinely new to say about them.
It'd be nice if the author was willing to change the license but it's not something one can reasonably demand.
I don't blame people using the GPL either (except possibly people that use it for libraries), nor people that publish apps on the various stores, I was just clarifying a point.
YMMV.
