many reasons, most people just keep their thoughts to themselves and never

tell them to others.Another form of self-expression is the written word.

For many people, it is easier for them to express their thoughts or

emotions in writing, instead of speaking them out. It is an especially

popular way for expression among shy and highly self-conscious

(自尊) people.People's thoughts are written down and then

published(出版) so that others can read and enjoy them. There are

many reasons why newspapers and publishers actually publish

people's thoughts, but the major reason is to give information.With

the introduction of newer technologies, new ways now appear to

share people's ideas quickly. Blogs are just one way.People can

now let the world know their hopes, dreams and day to day activities

through a web blog. Better than that, many sites allow customers to

words web and log. Slogging is the term that is used to refer to

activities relating to a blog, such as creating it, updating and

adding content(内容). And the blogger is the person who puts that

content on the blog.Blogs can be very powerful. Blogs can change

the world by changing the opinions of large numbers of people
