I think the best features Detroit papers ever had were "Action Line" and "Contact 10". One was a Freep feature, the other on the News [[don't recall which was which). They took questions about anything and came up with an answer, whether it was a road construction problem or a question about the history of the railroad tunnel. Made for interesting reading, and it gave Detroiters a source for an answer to a puzzle in those pre-internet days.
