Great content and fabulous energy!
There are some areas that could be improved:
For example, when taking about alternate syntax, taking a moment to demonstrate it would help out stick better in the audience's mind.
Like I said, the energy is fantastic, but better pacing and pauses will help get your content across.
I've seen Gary talk about the ServiceManager previously, but this time he really went the extra mile to understand the "how" and the "why" of its internals.
Good talk!
As a skeptical person, I am completely blown away by this performance!
Great talk, great perspective! Keep it on!
