http://www.readwriteweb.com/archives/when_open_data_is_bad.phpA very interesting and well-documented example of this empowering of the empowered can be found in the work of Solly Benjamin and his colleagues looking at the impact of the digitization of land records in Bangalore. Their findings were that newly available access to land ownership and title information in Bangalore was primarily being put to use by middle and upper income people and by corporations to gain ownership of land from the marginalized and the poor. The newly digitized and openly accessible data allowed the well-to-do to take the information provided and use that as the basis for instructions to land surveyors and lawyers and others to challenge titles, exploit gaps in title, take advantage of mistakes in documentation, identify opportunities and targets for bribery, among others. They were able to directly translate their enhanced access to the information along with their already available access to capital and professional skills into unequal contests around land titles, court actions, offers of purchase and so on for self-benefit and to further marginalize those already marginalized.
Certainly the newly digitized information was 'accessible' to all on an equal basis but the availability of resources to translate that 'access' into a beneficial 'effective use' was directly proportional to the already existing resources available to those to whom the access was being provided. The old story about the pauper and the millionaire having equal opportunity to purchase a printing press as a means to promote their interests can be seen as holding equally here as in the 19th century.

In a sector of the economy as dominated by political Libertarianism as web technology is, the idea that opening up platforms of data for innovation needs to include consideration of the unequal circumstances of potential consumers of that data is unlikely to be a popular argument. We tend to believe that the web and data are meritocracies, where anyone with enough motivation can create value and the tide will rise, raising all ships.
Maybe that's not the case, though. Maybe data as a platform needs to be presented to society with the same care that technical providers of Application Programming Interfaces (APIs) take in serving up their connection to a would-be community of independent developers. You want people to use your data? Then pay attention to what they need. Similarly, if you want all parts of society to benefit from the opening of public data, then simply opening it up and allowing the most ferociously competitive people in society to grab a hold of it may not be a good way to impact the world positively.
