Harvard classes on data science

It is interesting to see what Harvard considers to be data science. They use Python in all projects / training (there's nothing wrong with that, though exposure to other languages - R, Stata, SQL - would be great, in top of Python).

Data and visualization year in review, 2013

How can data scientists independently make money by selling data that is automatically generated: raw data, research data (presented as customized reports), or predictions.
