Mayhaps this video's thread would be a bit easier to find if the title says something like:
"Accelerating Through Angular 2 Video 3.6 (Models & Mocks)"
Or maybe there's another thread for errata?
I didn't notice this in other videos, but I suspect it's the same. At 2:55/slide 81, the title is "Our Component Architecture". This image made me confused until I realized that this is not an example of component architecture - it is directory structure (a file and folder tree). If this were displayed according to component architecture, it would look different, for example the video for Level 3, section 1/slide 61, titled "Component-based Architecture", we see a representation of the component architecture. The first representation (without this type of title) is in the first video/slide 22.
I know, I know, it's not going to get fixed. At least I've noted the error for others.
