I feel like this article gets a few things dead wrong - mostly that this trend originated in 2020. Maybe the term came around then but this is what dribbble design has looked like since probably 2010 or 2011 (which is also around the same time the flat aesthetic came around, a decade after this article claimed).
I've been saying this for so long. I realized at some point that the classes that had the greatest positive impact on my programming ability were always writing classes. Writing seems to engage the same part of the brain in a way that's just different enough to feel different. Even editing is a good lesson in refactoring. I'm always weary of any engineer who can't write.
That sense of the term was actually co-opted from what people are talking about in this discussion, i.e., rdf, microdata, etc. They are related though, as using the correct HTML tags was meant to be a first step into adding a layer of meaning to web content that wasn't there before. But "the semantic web" includes a whole, whole lot more than just semantic markup. Hope that clarifies a bit!
I do Web Design/Development, Python, some JS (+jQuery of course) limited experience with rails, and my obscure talent is that I'm pretty good at SPARQL.
