I'm not sure I agree. They are expert aggregators, but the real experts are the ones they are aggregating. You could say they are the best sources, but experts implies they have personal knowledge and I'm not so sure that's true. At least, not as widely as we seem to believe. And, in saying that I'm not saying they can't be experts if they became scouts or had a more narrowed field of study. I'm saying that given what they are doing, it's next to impossible for them to be experts on any given prospect.
