Mumbai: Seems like actor Ayushmann Khurrana is not happy with the growing trend of social networking sites as he belives that such platforms are 'transient'."One day Twitter will become uncool like orkut, it will cease to exist like Soviet Union and the value of followers will be like Rubles of the 1990s," tweeted the 28-year-old."Stop celebrating follower count milestones. Social networking websites are like artistes. New replaces the old order. It's just so transient," he further tweeted.Ayushmann, who became popular name after his debut film 'Vicky Donor', has close to 574,950 followers on Twitter.
