I just read a quite poorly written paper about the importance of communication.
When I was taught to respond to student writing, I was taught that I'm supposed to say something positive and then point out how to make the writing stronger.
All too often, it's tempting to make the positive statement something along the lines of "you've got a good idea, BUT blah blah." The "but blah blah" is painful, and makes the positive bit feel so minimal.
However, it's really hard to come up with positive things to write sometimes. This paper is a good example, because what I want to write is that yes, communication is important, and yours would sure be a lot better if you could write decently to communicate your point.
My upcoming committee meeting is looking quite appealing compared to this stack.
