Inline citations. I use perplexity all the time to find HackerNews or Reddit threads on certain topics, or conduct baseline research on topics. It will return the standard LLM answer but with inline citations which I can then use to verify or explore further.
Quality over quantity perhaps? Can't see why you'd want _more_ than about 3-5 sources returned each time. Anything more is information overload and defeats the purpose of being able to vet the claims in a timely manner.
