Have you ever collaborated on a doc in Google and wanted to communicate with the other editors, but they weren't in the doc when you were, and you didn't really want to construct an email to them? Enter Discussions in Docs!
I have used this feature in the past couple weeks to collaborate with other members of a committee. We really didn't have time to meet face-to-face, and wanted to avoid throwing comments all over the document. We were in a time crunch so commenting felt like a waste of time. So...we used discussions and whenever someone wanted to communicate a thought to the rest, whether it was through a comment or through the discussions tool, we all were kept informed of the flow of the document. It is really a neat addition to docs and I encourage you to try it! Not sure it is for you? Watch this short video:
