Really depends on the topic. If you're searching for "water business", the results are amazing: there's pages explaining at length the difference between each subtype of businesses, shop aggregators and ranking, even people discussing the service providers, etc. I agree that that mentioning sources isn't a priority but that's the exact same thing in the West save for research papers.
