It is frustratingly difficult to get biomedical scientists to openly discuss the work in their field. PLoS tried to have discussion sections to papers, and Nature has tried various approaches as well. Neither have worked. I looked-up my favorite topic (a popular one) on Plasmyd, and found 20 papers, none of which had a single comment associated with it.

It's honestly a vast waste of intellectual potential, I wish I knew the solution!
