If you create a webpage that has 10s or 100s of different answers to questions for a topic, and it saves everyone time researching; then I would consider that useful and not spam. Just my opinion of course. And I'm not saying this is a substitute for creative content, and I don't think it is an either or. Informative content vs creative content is just different in my opinion.
