Decide if we want to include publishing costs

[matiasandina]

I found a quite dirty dataset of publishing costs for journals (both open access and not). Most journals charge more for publishing open access. We talked about papers doing the math that it's eventually cheaper to publish open access.

Should we include this?

I think it would be a good thing for a "call to action" for the community to lower costs and to bring agencies to help subsidize or lowering the costs and eventually force open access (but maybe off topic).
