making suggestions for open access advocates...
Labeling different open access types as “green” and “gold” is not helpful.
I like read about scientific publishing and the issues around it, but branding the different kinds of access by colours is so completely arbitrary and random, that even even I can’t remember what the difference between “green” open access and “gold” open access is. I have to look it up every time.
When people can’t remember the terminology, the message is not likely to be persuasive.
