I think that blogs are not necessary, in my personal opinion; I don’t like blogs, because you have to dedicate them a lot of time. However, I have to say that this blogging experience improve my English, now I can feel that I’m a better writer; moreover, we learn a lot of new things. I don like post to others an that kind of things, but I did all work with my blog, I mean, I commented to my classmates and I did my post.
In some cases I felt that this activity was funny and sometimes I enjoyed posting to others, because when I read my classmates’' opinions I always was laughing about things that they said. I think that this writing process was very good for me and all my classmates, because now we can write well than before (at least in my case).
