"Thanks everyone, this is really sweet didn't expect such a warm welcome. Love to you all," he added.
The superstar was hardly seen on big screen in 2009 except in "Billu", and explaining the reason behind his absence, he wrote: "Injury has kept me away from making more films. Will work my back off to be around more... the shoulder feels strong and so do I."
"It is really a very satisfying way of communicating with the world outside your immediate circle. I've been persuading all my friends to get on Twitter. Shah Rukh finally relented," Karan told. The star is already hooked hopelessly to Twitter and hopes to establish a personal rapport with his fans and movie-watchers in time for the release of "My Name Is Khan".
Right now Shah Rukh is enjoying his holiday with wife and children.
"Kids and life calling...watching Tim Burton's '9' (animated fantasy film directed by Shane Acker) with them...last holiday...so up late...catch up later...," he wrote in his latest posting.
By joining Twitter Shah Rukh has joined celebs like Priyanka Chopra, Abhishek Bachchan, Imran Khan and Karan Johar who are regular on the social networking site.
