Corey Haines says about Katacasts:
The Katacasts series consists of performance katas, done as screencasts, by Enrique Comba and me, Corey Haines ... to provide inspiration for others to gain benefit from using katas in their own practice.

I'll read a book and summarize it on my blog.
If I remember things I read during my work day, and can apply them to make better decisions, then the book reading session was a success.
Periodically I'll go back to my book reviews and see if I'm still using what I learned.
