What do you want to see in publishing? How to change it?
Understand what is going on, the economics of it.
Political not technical.
Start a revolution - boycott specific journals, preprint everything, review the preprints. But who will do this?
Preprints are a quiet revolution, mor accessible to the scientific community than boycotting journals bottom up change.
Fear of preprinting due to journals not accepting it. See Sherpa/Romeo for a list of preprint policies by journal.
Fear of preprinting due to scooping - other researchers do my research and publish it before me. But we already share our research at conferences, sometimes it happens but it's rare. Plus some journals have "scoop protection" - see your preprint as priority.
How difficult is it to get feedback and reviews from people who are not your colleagues? Only 11% preprints on bioRxiv have comments, some might get feedback by email. Are preprints lost in the ether?
