OK, you more or less agree with my argument. Enough about that, then. I am curious about something else. Do you have non anecdotal information about Wikipedia

OK, you more or less agree with my argument. Enough about that, then. I am curious about something else. Do you have non anecdotal information about Wikipedia's general dependability? How is the dependability for large subjects? For subjects like a poet where less than a hundred people even recognize the name? (The last I saw on this was years ago, when Wikipedia edged out the Encyclopædia Britannica. It would be strange to be less dependable now?!)
