I think twitter is a very socially helpful network as you are closer to the truth. You get to know your favorite celebrities' life updates and you can easily communicate with your friends. It competes with Facebook. Each week, there is an article about the top 20 tweets. It is published on billboard.com. It gives you all the best tweets of the celebrities. So for example, this week's top tweets are by Justin Bieber, Rihanna, David Guetta, and many others famous people. I really enjoy readind this article evrey week.
