It is hard to say much about such good blogs.
The first blog I'm going to mention is Sammie Jo's. All of her responses are very detailed, long, and intriguing. She talks about all aspects of what she respond's to. Her responses are very well written, and make the reader think more deeply.
The second is Emma's. Like Sammie Jo, her responses are very meaningful and deep. She points out that somethings like the poem "Starry Starry Night" by Anne Sexton could have double meaning. She real digs deep into the meaning of the text.
The third blog is Fatima's. She, like the two before, clearly thinks very deeply about the text when writing responses. Her posts express opinions of her own, and also explore other ways people could view the texts she reviews.
