I'll grant, the audience for the post is pretty niche, but if you're an aspiring SQL dev, it has some strong examples using window-functions (including named window-functions² which I don't often see in the wild, since it's only become more available in the last 5 years or so).

But the underlying "these are important signals to monitor" was equally interesting as the technical/SQL aspect. Glad you enjoyed it too!
