Last week,I did a survey of 1000 high school students in Guangdong about " What do you think of blog?" By talking with them,I found that 70% of the students supported it while the others against it.The supporters believed using blog can express their thought freely,and show themselves as well.Therefore,blog is a good platform to make new friends.On the contrary,other students didn't think so,they pointed out that in blog,personal information is open to everybody,so it's easy to discourse of it as well as get deceived by it.
