One thing we do a lot of at Puppet Labs is release product. And every time we make a major product release, I have to go through and update our training material. I validate all the exercises and examples and code snippets. And when we make UI refreshes I have to take all new screenshots. That doesn't sound like much--it's just taking some pictures, right? Well, yeah... but what am I going to take pictures of? Just firing up a master and screenshotting away isn't very interesting or informing.
