It would carry more weight to someone who has never heard of Substack or doesn't know how big a company it is. They'd assume it was a large company because of who was reporting about it.
Someone has to read and like your PR to approve it. Presenting your work as a series of simpler steps helps the PR recipient (and you!) mentally verify it.
This is very reminiscent of Wendy Carlos's "Switched on Bach". If you liked the video, but have never heard the album, I recommend you track down a copy. Tragically it never seems to be available on streaming services (at least the ones I subscribe to).
Anna von Hausswolff has done some great work with real church organs too.
It's likely the Firefox developers use more of its shortcuts because they are more familiar with the product and are more interested in optimizing their workflow than a typical user. Exploring, which includes backtracking, is the core of the web browsing experience so I'm not surprised people are doing that far more than, say, searching for a substring.
It's also worth pointing out there isn't a great opportunity to learn the keyboard shortcuts Firefox provides. Traditionally you'd learn shortcuts by seeing them next to menu items, but the menus are hidden behind the Alt key, and many actions simply aren't listed there. For example, "Find Again" / F3 is omitted.
One of my kids learned Scratch at home. He tried some local classes, hoping they would teach more advanced material, but they were introductory and he spent his time tutoring the other kids (not a bad lesson in itself!)
We briefly tried GameMaker Studio 2, however we had no prior experience and finding out what functions were needed or called made it a high friction experience.
He has been playing Minecraft since a young age, and creates elaborate redstone mechanisms. I like how this mixes creativity, spatial planning, and boolean logic, and doesn't require learning a new UI or language.
Most recently we tried creating a Minecraft mod in Java using Forge. I cannot state strongly enough: do not do this. The Forge architecture is fundamentally broken, whereby it adds some functionality but otherwise forces you to code directly against decompiled Java classes.
Most tutorials only work with a specific version of Forge/Minecraft. There are no release notes or documentation, because there is no API. (To be fair, the Forge aspect is documented, though I only found it useful once I already knew what it was trying to explain.)
So what started out as an exciting father-son project became something I dreaded.
