The Reasons Why Friends Don't Comment Other Blogs ?

As we discussed about this topic in class, there are many reasons why one does not comment on other blogs. From my opinion, the reason is that we have no need to put comment. When I read my friends' blogs, I just yes, understand, so-so and leave it. I think that we have not to comment anything. There are many other reasons that my friends told in class. 

Firstly, when some of friends read other blogs, if they think in the same way with blog owner, they will not comment. On the other hand, if they think opposite with their friends, they will not comment too since they are afraid of argument. 

Secondly, they wait for the first person to comment as if there are no first comment, they will not be dare to give opinion.

Thirdly, they have no time. As I mostly knew my friends before studying this class. Therefore, I knew that some of them are management committee and some of them take many difficult courses in this semester. Conclusively, they may have no time to comment, just read through the blog.
