The Times of India has another example of what cell phones can do for a society. Through the website IndianBloodDonors.com people can now send a text message with their urgent request for blood. This is clearly a much more direct means of communication than first finding an internet-connected computer.
Getting the cell phone in the hand of the end user is just one necessary aspect of makin gthis work. Building the website and system of donors, screening the blood, and informing people of the available service are probably more difficult. But the new technology brings new opportunites.
