How should blogs be graded?

How should our blogs be graded? Well, I think our blogs should be graded on how elaborate we expressed our opinions and if we answered the questions fully. Grammar and vocabulary should not be graded BUT if there are words like "deez" and "da", there should be a couple of point deducted because that is just ridiculous. These online journals are a chance to show ideas and opinions in a new and improved way; as long as the task is accomplished, an A or B should be given.
