Powerpoint is how the information is presented. Her post is all about how using a chalkboard leads to a better presentation of the material and increased focus. I like to teach using the chalkboard or whiteboard, and prefer learning that way as well. There are some use cases for slides. A picture or graphic too complex to be drawn on the chalkboard. Animating an example (I've seen Steve Jobs use this to good effect). In my lectures I strive for a minimal slideshow, lots of chalkboard examples, and live demos of example code.
