Citing sources isn’t usually called for unless trying to present something as one’s own work — man on the street questions generally don’t rise to that standard. They also lack a profit motive. Citing sources is also, traditionally, a key method of separating the work you built upon from the work you yourself derived/created/expanded. If one does not cite their sources, there is no way to establish if the presented work is their own, or copy+pasting someone else’s.
