It stimulates thoughts about what a basic unit of publishing might look like, and much of it resembles a nanopublication: There is an assertion (the blank page), along with provenance information (unsucessful treatment of writer's block, as per the title), and there is bibliographic metadata (Dennis Upper (1974) The unsuccessful self-treatment of a case of ‘writer's block’. Journal of Applied Behavior Analysis, 7:497.). The footnote and the review could in principle each be a separate nanopublication.
