From Lisa Janicke Hinchliffe in The Scholarly Kitchen:
Like many others, I found myself reading response after response after response to cOAlition S’ call for feedback on the Guidance on the Implementation of Plan S last week. The volume of response is staggering. Statements have poured in from individual and groups — publishers, scholarly societies, disciplinary repositories, scholarly communications platforms, funding agencies, publishing professionals, libraries, library associations, and researchers themselves. As the deadline drew near on Friday, I could hardly “right click/open link in new tab” fast enough as my Twitter feed scrolled by. The input from Norway alone has reached 885 pages. The Open Access Tracking Project currently has almost 400 documents tagged oa.plan_s. reddit Open Science and Scholia/wikidata have also been tracking replies. One imagines that there is feedback that has not been shared publicly as well.
