It's a free download, so I'm not making any money off this at this point. I really should read Chris Anderson's book Free and find out more about this business model, but his book costs $26, so I'll have to check the library.
Anyway, I'm giving it away for free on purpose. Even charging one dollar would establish a significant barrier to downloading the thing, and I suspect the download count would be closer to 14 than 1400. So, I'm basically giving up $14 in order to get my idea seen by 1400 people.
As I learned from Exposure, the value of an idea increases with familiarity. So, the more people are familiar with the concepts in the Simplicity Cycle, the more valuable the idea is (and the greater the possibility of someone eventually hiring me to do stuff because I'm the Simplicity Cycle guy). Plus it's just fun to think that 1400 people have clicked download and (hopefully) read through the thing. I think that's cool.
