Social Web Mining Economics Data

I am interested in mining some web-data related to the rupee versus dollar rate ...

I would like to know what kind of information is out there ...

What are people saying about viability of the dollar ...

What are people saying about viability of the rupee ...

What about the international analysts ...

What are they saying about India's GDP growth rate ...

What are they saying about India's retail reforms ... and other reforms that the West is expecting from India ...

That is the kind of information I am looking forward to ...

I'd love to hear from anyone ... how to do all the above and of course ... there are more questions than those above ...
