I strongly agree with Axel Bruns about Facebook’s forthcoming API changes:

While these changes may generate some positive publicity for the company and its beleaguered CEO Mark Zuckerberg, they are likely to compound the real problem, further diminishing transparency and opportunities for independent oversight. The net effect of the new API restrictions is to lock out third parties and consolidate Facebook’s position as the main analytics and advertising broker. Contrary to popular belief, these changes are as much about strengthening Facebook’s business model of data control as they are about actually improving data privacy for users.
