While blog preserving my observations and thoughts, it preventing me to spend enough time to read what other people thinking and saying, so I created almost 2 years ago the extension of this blog in the form of 2 Google+ pages
http://tinyurl.com/VisibleData and

“Money is not the only reward of education, yet it is surely the primary selling point used to market data science programs, and the primary motivator for students. But there’s no clear definition of data science and no clear understanding of what knowledge employers are willing to pay for, or how much they will pay, now or in the future. Already I know many competent, diligent data analysts who are unemployed or underemployed. So, I am highly skeptical that the students who will invest their time and money in data science programs will reap the rewards they have been led to expect.”:
