I am going to tell you how to make a good comment. First, you read their blog and think about what you liked. Then you would say something you liked about it. Then you think about what they could have done to there blog to make it really good. Next tell something that you can refer to in real life. Make it positive and not make them feel like they did not do good. That is how you write a good comment to someone.
