It's been more than a week since Ratan Tata returned as chairman of Tata Sons replacing Cyrus Mistry. Evidently, Tata is too busy trying to deal with the aftermath of Mistry’s unceremonious exit. While he is not one to tweet his views regularly, one would have expected Tata’s handle @RNTata2000 to have been updated. But it still says: “Former chairman of Tata Group. Personal interests — aviation, automobiles, scuba diving and architectural design.”
