I agree. When someone posts an amazing quilt, and there's already 4 or 5 pages of everyone describing how wonderful it is, I usually can't think of anything new to say.
Also, I probably also don't want to become an over-poster. I have a few of these on facebook. They just HAVE to respond to everything. Fortunately, that doesn't seem like an issue here. I've never noticed anyone monopolizing the responses.
