Updated: the updated version is now live on Amazon.com (9pm mountain, 30 Dec 2012)
Evolve, Part 2: Incentives has been heavily edited for typos. It is in the process of being re-published by Amazon. Probably later tonight or tomorrow it will be updated. I will post again when the revised version is live on Amazon.com.
Previous purchasers: I have asked Amazon to push the updated version to all previous purchasers. This process takes about 4 weeks. If Amazon deems the update worthy of pushing out, then it will happen automatically. You need to have your account set to receive updates (not sure if this is set in your Amazon.com account or in you Kindle but apparently you can set this to block updates or receive updates).
