For those of us trying to get a handle on the Facebook/privacy debate, blogger Matt McKeon has created a useful infographic. This displays types of personal data on Facebook and how over time access to has been extended from friends to networks, to all Facebook users, through to the whole internet. You can click through and see the changes from 2005 through to April of this year. It's a neat way of presenting the issue.
Matt is a developer with the Visual Communications Lab at IBM's Research Center for Social Software. He believes the increasing permissiveness of Facebook's settings over the years "has largely been part of Facebook's effort to correlate, publish, and monetize their social graph: a massive database of entities and links that covers everything from where you live to the movies you like and the people you trust."
However, he's also keen to point out that "I like Facebook. It's helped me reconnect with dozens of people with whom I'd lost touch, and I admire the work their team does. I hope your takeaway from this infographic isn't 'I'm deleting my account'; rather, I hope it's 'I'm checking my privacy settings right now, and changing them to a level with which I'm comfortable'".
