If we expand "tech" to mean "technical" rather than "technology", those statements become much more likely to be true. People who have skills in some sort of technical background seem much more likely to have interesting insights than people who do not. HN loves to post Slate Star Codex, for example, and I doubt most here have the skills in psych to effectively evaluate his writings as correct.
Maybe but when you go from a very low likelihood to begin with increasing it even 10 fold might not make a practical difference.
The point was any one of us here can accurately judge content on a handful of topics in our areas of expertise and to a lesser extent in connecting fields. But we can say next to nothing outside of that. Let alone generalize to "all" platforms and "99%" of content. It's not "tech"/"non-tech" but "what I know"/"what I don't know".
> interesting insights
How would one even realize this if they're an expert web developer reading a blog on astronomy? Every single article on a platform could be either gold or shiny manure and most of us wouldn't really tell the difference unless they solidly overlap with those topics mentioned above.
You are def right that I should not pack everything in a non-tech cluster and call it crap. However I'd still keep my initial statement, it's a simplicatiom but it's true.
Of course there are and must be great blogs in non-tech areas but they are not that many. Writing high quality blogs for free seems not be common in other fields. Often people rather publish the findings in a protected space, call it academic paper and I can read just a lousy abstract. Actually most academic non-tech fields fall in this category.
Your second statement might more accurately be formulated as "I tend to find the insights of people with a technical background more interesting", or even "I am more capable of understanding what is interesting about the insights of people with some sort of technical background even if it is not my own." Otherwise, you're claiming that there's something objectively "uninteresting" about, like, the majority of human insights that civilizations have ever had and found valuable.
