I prefer public conversations for the reasons that Brian Tomasik does.
Can we continue to discuss other considerations here?
Alright, let’s try.
For cons, I would say there’s different methods of doing PR, and different EAs have different takes on it. See for example this discussion. So one agency might be problematic for this reason.
Another con is that there are already a number of EA orgs doing public outreach—EA Action, TLYCS, InIn, GWWC, etc. So they would need to coordinate, which would be pretty difficult.
Not sure what you meant by “Systemic Risk” for cons.
For pros, I’d add long-term campaigns due to centralization of resources.
