I think that your blog is very good . First of all your posts are suprisingly long. You usually don't look like a pearson who like to talk much. Your posts are pleasant to read becouse of your writing style. When I'm reading your blog I fell like I'm listening to the interview rather than just reading. It's clear that you pay attention and concentrate while writing. Your posts didn't change much since the beginning of the term but I don't think that they really need changing at all. I don't see any big grammar mistakes (probably becouse I'm not very good at grammar), but sometimes your posts are slightly chaotic and unorganized.
To sum up your blog is well-written and I found it very interesting. I think that you are one of the best writers in our class.
