This closes no open issues. I just saw an opportunity for improvement.

When I watched the intro videos of this project I naturally got excited to try it. It took me far too long to get the example of extracting valuable information from a Youtube video working because the information in the intro video is outdated already. Daniel used a utility called "pt" which is now called "yt". It's a subtle PR but one that might might get others to try out a great example pattern of Fabric sooner.
