>Rational discourse is recognizable as well written, insightful, humble, reflective, self-countering, anecdotal etc. By "search is terrible" I mean with respect to finding this.
I believe a search engine that ignores results based on superficial and aesthetic qualities like "modern web design" would be even worse in that regard, unless you're assuming no relevant discourse about any subject has taken place on the web since the early 2000's.
I admit, I have no idea what heuristic you would actually use to find "well written, insightful, humble, reflective, self-countering, anecdotal etc" content, but I've seen it on modern sites (even on Twitter,) and I've seen a lot of garbage on old sites, so a simple text search of only old websites doesn't seem like it.
It is fun, though.
