A journal was a thing when it was based on paper. What value does collecting papers to a specific issue of journal have today? Science and Nature may attract better peer reviewers but maybe we could find a new way to compute a weight for a paper depending on the people who peer reviewed it instead of the journal it appeared in? What if we could look at authors, peer reviewers and papers as a graph of weighted edges to come up with a score that was independent on journals as a concept? And where there is an ontology for the semantics of edges (not only number of citations)?
