Incidentally, any idea what they key on for pot?
Yeah, it's called pot.
If it is worth paying for someone will pay for it.
So you're saying give it for free and offer a link of some kind where somebody who feels like being "fair" will go through a set of hoops to pay for something that they were just given for free? While you might find some individuals that will actually do this, they are in the extreme minority.
Hint: Even when it's entirely free, most people don't even want to go through the hassle of signing in/up with a free account to view the content, instead just moving on to another site that doesn't hassle them.
