Teachers sell their lesson plans. School districts ask for a piece of the action.
I don't really know what I think about this. I've bought stuff from people who are better at making stuff than I am. I don't really have anything I'd want to sell, but I have stuff I probably could sell, if I format it differently. So I don't really see anything wrong with it.
But the music industry just lost the "selling content you can find for free on the internet" fight. The movie industry is ripping itself apart over the same issue. I'm not sure that I'd want to wade into waters that somebody else has already filled with chum.
So I'm not sure where this goes.
