But then the "blog post" in the old example and the "article" in the new one belong to a different type of artifact, right? It's a bit like the distinction between "programming in the small" and "programming in the large".
While belonging to the same medium and often done by the same people, they prioritize very different aspects.
I'm not looking to draw a general distinction between the terms, but rather just saying that there's a qualitative difference between a thing you write and publish in a single afternoon (or even a single lunch break), and something you research and prepare over 6 months. Many people routinely do both and are good at both; neither is inherently better, but they are different things.
