The craze of social media has finally ended up consuming the Iron Man. Robert Downey Jr who plays the popular American superhero, who had hitherto stayed away from social media had to ultimately given into the lure and join the buzzing Twitter platform. While his first tweet was a simple, “ Talk to me Twitter,” his accompanying handle identifier was carved out in true Iron Man style. ‘You know who I am.” Now that sounded more like a threat rather than a request. Not that anyone is scared. In less than nine hours of joining Twitter, Robert garnered more than 6,25,000 followers. Enjoying all the attention the new platform was affording him, Robert later wrote: Loving all the love, folks. It's been a blast. Though can somebody please explain how anyone can keep their thoughts to 140 characters or le Looks like Iron Man will have a tough time trying to squeeze his thoughts within 140 characters. May be JARVIS( Iron Man’s artificial computer intelligence program) can lend some much needed help there.
