If a class would want to be a part of quad blogging, I would tell them that we post good comments on their blog and tell them what we were/are learning. Then that will tell them what to do when they start.
What makes a good comment is adding encouraging things and telling them what they can improve on.
What I like about quad blogging is that you learn what other schools are learning about.
This can help us in learning by the symbols, language and text.
I really don't think that any changes should be made.
