Some examples to get started: * Sources of quotes that are hard to find Google and other quote sourcing sites, e.g. William Inge's “We have enslaved the rest of the animal creation, and have treated our distant cousins in fur and feathers so badly that beyond doubt, if they were able to formulate a religion, they would depict the Devil in human form.” * Deep historical questions, e.g. what factors drove the wealth difference between North and South Europe in the Early Modern Era, what effect did religion play in this? * Interesting scientific question, e.g. it's always said that light's speed in medium is slower than in vacuum? Is this a correct statement? If not, why did the misconception arose? * Literally gossip, e.g. was Emily Dickinson bisexual, gay, or neither? All explained in a (relatively) jargon-free language, with references, similar to what Quanta does for science and math.
