Would it be worthwhile to create an index where people that are experts in something could vouch for the journalists that seem to know what they're talking about?

E.g. I can verify that on the information security topic Joseph Cox from Motherboard is constantly on topic, but that information is useless to me personally, because by the time Vice publishes something it's already old news for people in the industry (or anyone following infosec twitter really). But that information could be useful for someone else and in return I would like to know which journalists actually know a thing or two about say ML/AI or astrophysics.
