I was Googling for the potential applications of data science. My search was inspired by the fact that India has a government data portal - data.gov.in . Soon, I was delighted to find that since my last look at the topic, something new has happened. It is - http://www.opendata500.com/ - which is really a list of 500 companies who have created businesses out of open government data. Now, that is very encouraging ! Because, like many I too am a believer that any sustainable human endeavor should also make economic sense (there are a few but, very important exceptions).
