The lightning talk is a really great sales pitch, but it's unclear how to actually replicate it. Another video of his, a recommended one after the lightning talk, again loses me a little and goes very fast. I could pause and try to understand... but it's not just about how to do it, but also about knowing that I should be looking to do certain things in the first place.
Your tutorial both gives a nice overview of what features exist, and explains very clearly how to do things. Thanks for taking the time!
