That sounds fine, though I'd add the consideration that the further someone is from your field, the more that an arbiter and a highly filtered reading list become necessities. A scholar in another field isn't part of the daily conversation in yours and doesn't have time to get involved or read up on on it - and, without arbiters, they'd need to do in every field except their own. And the scientifically literate public has no hope - will they find the Western University list? For every field they're interested in? And read every list in every field?

A few central arbiters of the best research - e.g. Nature and Science - make science accessible outside your field, and outside professional science. Even reading those two publications is too much every week, with all the other reading, other activities, family, responsibilties, etc. on top of career.

> I just don't want them to be organised around journals because journals are toxic and lead to concentrated power over scientific narratives.

I don't care if it's journals, though people often assume that shifting power away from the current flawed institution to a new one will resolve the problems. The probems are inherent to power itself. We need a different structure with different incentives if we want a different outcome.
