This week's cartoon was drawn by Karen Chee, an 11th-grade student at San Mateo High School in San Mateo, California. In Karen's cartoon, people are lining up to be turned into cash by a machine labeled with a big "f." The machine stands for Facebook, a social networking website. People go there to exchange messages, post photos or see photos that other people have posted, or even play games. How many of you are on Facebook? How many of you use it every day?

If you do use Facebook, you are one of more than 900 million other people who use it, too. Facebook is the most popular website on the Internet. The cartoonist here highlights one reason for Facebook's popularity — it doesn't cost anything to use it. As long as you can get on the Internet, you can sign up for Facebook free.

Even though it is free, Facebook makes a lot of money. Last year, the company made nearly $4 billion. Many people have wondered how Facebook can make so much money by giving away its product for free. The answer is advertisements. Companies pay to put their ads on Facebook where hundreds of millions of people see them. Facebook also makes money by watching what you write on your Facebook page. If you say you like cupcakes, you'll probably see an ad for a bakery. This is what the cartoonist means by saying Facebook is turning "you" into cash. Do you think this is a good editorial cartoon? Why or why not? How do you think the cartoonist feels about Facebook?
