Response to the Questions in John's post

I think that certainly technology is very useful,
but it has many negative effects.
John said negative points of technology on his blog.
I have a private blog, most of my friends also have it.
Friends of mine and I posted many articles.
Some people posted someone's abuse on their blog.
I think that doing so is very sad things.
If a person who was said bad things see the blog,
a person feel very sad, and feel angry.
Now, there are many murder cases caused by such things.
Even a boy who is a elementary school's student,
he kills other person. It is very sorrowful thing.
Many people use Internet, but it sometimes frightening.
Although people have developed technology,
I think that is not always good for us.
