I wouldn't say I have an uncommon take on RDF. I feel it gets more focus (maybe too much) in semantic web related academia and research than it does on the general web. And the substantial thing wasn't meant to be that harsh of a critique, but like another comment mentioned, sometimes these 'introduction / wiki articles about __' are a bit of a tease, and I wish someone were posting something more novel.

As for what I'm doing, it's a project that is taking various siloed fan-created data on the web and collecting, aggregating, and transforming it into RDF for the purpose of being queried by researchers. I think RDF and RDF-adjacent things (e.g. knowledge organization, ontology application) are useful here, but the actual querying / data analysis requiring an RDF transformation is maybe questionable.

How about schema.org and the extent to which most websites now implement RDF in the form of schema.org

How about Wikidata?
