So how to begin to fix the problem when there are no new resources?

How about if museums and archives were to offer free access to content for a cadre of bloggers on Steemit aimed at generating interest and discourse? That would cost little to nothing and would leverage this new form of social media. And the bloggers (presumably people entering the field) would have their own dedicated funding streams.

Traditional social media, as we know all so well, does not pay. Steemit does.
