The whole SMS thing is a ploy by the mobile services companies to make money. Millions of Indians (read fools) SMS their candidate and in the bargain the mobile services companies make pots of money and there is a profit sharing arrangement with the TV channel and the Producers of the show. An Indian Idol (or any Idol) cannot be chosen by mere votes of ordinary people, vast majority of who do not know much about music. The verdict of eminent judges like Javed Akhtar and Anu Malik should be final - that chosen person can truly be called Indian idol.
