Honestly although I've occasionally derived benefit from these, I think I'm reaching a tipping point where I feel the plethora of how-to articles with their ads and newsletter pop-ups and everything are less productive than just some plain old documentation and taking the time to fundamentally understand the tech so that I no longer need the how-to. Mainly because I trust Kubernetes to keep their documentation up-to-date but who knows how current a random how-to article is, never mind the marketing bloat they're usually polluted with.
