I've been thinking about using Google Docs to share a novel with a few beta-readers because it is simpler than sending every one of them a separate text file and keeping track of the comments across files.
For this to work, though, I would need the comments of each reader to be visible only to them and to me, so they can't relapse into a "herd mentality". Each of them should read the novel and comment by themselves, with no influence from the others.
Is there any way to achieve this in Google Docs?
