It's a type of prisoners dilemma with Google. They're having to out game the SEO gamers and pick a tactic that moves the web forward and doesn't over reward entrenched parties. I agree this site gives good useful information, but what if new glues come out on the market? What if a YouTube channel comes out comparing and testing glues? Authority is great until it's out of date, so I think it's logical to go with a bias towards fresh content.
I do wish there was more of a focus on attribution and citing sources on the web. Maybe Web3 will save us on that front...
