In editing groups, members mark on the manuscripts—either with a pen, or on the computer they use comment boxes in Word texts. They do that before the meeting, and no one reads manuscripts aloud at the meetings. With the proliferation of the Internet, more groups are moving into editing each other on-line.
I detest critique groups and I'm quite vocal about objecting. Writers spend half the meeting time reading aloud the manuscripts and members make comments. I consider that a waste of time. We write for the eye not the ear (with the possible exception of poetry). Some writers read their manuscripts aloud to listen to the cadence and pick up sentences that don't flow, but that's different.
Editors don't sit and read submissions aloud. As their eyes race across the page, they recognize the quality of the writing.
We help other writers when we edit them;
we rarely do much good critiquing when they read aloud.
