At first glance, Oprah, Lady Gaga and Sarah Palin have little in common. Dig a little deeper, however, and it seems that they do: all have tweeted through Twitter. This caused Conan O’Brien to poke great fun at celebrities being so self important.
However, once he lost the Tonight Show, he lost contact with his fans and retreated to Twitter himself, saying that it saved his life.
2010 was a banner year for Twitter. 100 million people tweeted over 25 billion times. However, the site stills needs to be able to make money and improve their product. To that end they have introduced promoted Tweets, which can cost as much as $100,000 for a 24 hour period. They became a phenomenon last year. Only time will tell if they get the money to keep up with the popularity.
