When I was a little girl, the greatest show on earth was the Barnum and Bailey Circus. I loved going to the circus with my family. But, today the show has shifted to the Web. Billions of people from all over the world converge on the Web to exchange information, ideas, beliefs, thoughts and opinions. My favorite show on the Web is Twitter. People from every walk of life gather in the ultimate melting pot. Sitting here with my cup of coffee, I am enjoying reading about my favorite stars, rockers, politicians, models, sports teams and world news. What is your favorite show on the Web?
