I have no insightful information to give you with regards to Monero, but to me what you're looking for is a good fit for Marginalia's text-centric search engine [0]. I get interesting results when I'm looking for authentic and elaborate opinions on given subjects outside the beaten path, which seems to be your goal. And especially useful when trying to flee the cesspool of results Google gives you when looking for topics with heavily financial undertones - good effing luck getting to a genuine article speaking of cryptocurrencies, stocks or any topic with financial incentives.
