Lady Gaga's Twitter Account Is Worth $30 Million, According to Some GuyS

Is Lady Gaga's 20.7 million-follower Twitter account really worth $30 million? That's what some marketing expert quoted by the Wall Street Journal claims. He says the "publicity and direct access Twitter gives Gaga to her fans is worth around one-third of the $90 million" she earned last year. I would have this marketing expert evaluate my own Twitter account for comparison but I already know its worth: $9.78 and a bag of Kettle Chips. Any takers? [Image via Splash News]
