Why should student blog's?

I think that this is a another ways to learn things. And is a part of enjoyment to learn.so it will not too tired and the student will be more interesting on the blogger and the homework so i think is god that to have student blogs.and can help student to learn english and practise tiping english and sometimes someone can give you a message to say something or tell you how to write it better so you can learn to write some news in the blogs and learn english.and this is a way to learn english too!.
