Governments and public officials are rushing to embrace the concept of Open Data, throwing open the vast panoply of publicly collected information for the digitally savvy to mine and exploit, writes Ben Rooney in the Wall Street Journal.

However, the use of government data throws up many issues surrounding privacy, policy-making and the uses to which the data has been put. These need to be tackled before simply opening up these digital to all comers.

Some remarkable quotes:

“Anonymized personal data has to be treated as personal data and not open data.”

“The main problem with correlation is that if you look at enough data you can find correlations in almost anything.”

“It is very dicey when you start talking about causation… You know, we have real problems to solve.”
