Get your facts right , I think you are under all false impressions, Banglore and Hyderbad since ages have been next in line after the 4 metroplexes , and its just the computer boom that has helped these 2 cities boom. Going back to traditions and culture which I beg to differ has no hand in this progress, if sometthing you have to be thankful to then its dollars and pounds and not kathak and bahart natyam as you mention in your article. First rather than making it south and north think of India as a whole country . Its people like you who create prejudice.
