It tells us there's an effectively unbounded amount of possible things to read on the internet and a lot of it is crap, debunked, hidden behind interstitials, paywalled, sales/marketing content dressed up as blogs or otherwise not worth interacting with.

In case it wasn't obvious, my answer is no in about 95%+ of cases. The comments serve as a pre-screen to determine if there's anything unexpected/interesting on the other side of a mystery link. Someone has already done the work of reading and forming a response, I'm going to re-use their (combined) effort.
