                                                                  Blogs (博客)

     A "blogger" is a person who writes on an Internet website called a "blog". The word "blog" is a short way

of saying "web log", or "personal website". Anyone can start a blog, and they can write about anything they

like.

     There are millions of blogs on the internet today. They provide news information and ideas to the people

who read them. They contain links to other websites, and they provide a place for people to write their ideas

and react to the ideas of others.

     A research company called Perseus has studied more than 3,000 web logs. It says that blogs are most

popular with teenage girls. They use them to let their friends know what is happening in their lives. The study

also says that more than 100,000 bloggers stopped taking part in the activity after a year.

     However, some people develop serious blogs to present political and other ideas. For example, the

Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And

American companies are beginning to use blogs to advertise their products.

     At the same time, some long-standing blogs have ended. Last week, blogging leader Dave Winer closed

his free blog service "weblogs. com". He said the site became too costly to continue. he started the blog four

years ago, and thousands of people had written on it. They are now upset because they did not know that the

site was closed.

     One blog that is still going strong is called Rebecca's Pocket. Rebecca Blood created the website in 1999.

She wrote about the history of blogs on the site. That article led to a book called The Weblog Handbook. It

has been translated into four languages so far.

     Miss Blood says Rebecca's Pocket gets about thirty thousand visitors a month. She writes about anything

and everything-politics, culture and movies. She recently provided medical advice. And she wrote about how

to prevent being stolen from online bank accounts.
