Sunday at brunch we had an interesting conversation about Facebook.

Establishing the appropriate privacy levels to the various constituents see appropriate material is hard. So hard it takes a long pages of text and screenshots to just paint a picture of what to review for the top 10 Facebook privacy settings.

We were discussing how to make the Facebook world we touched more private. How to keep those we supervise or those who supervise us at bay once accepted into our social circle. Few of us only post things our grandmothers would find acceptable, so how do we ensure grandma will never see that picture? This meant banning grandma from seeing the Wall or photo albums or tagged photos.

I had heard we would soon be able to change the privacy levels of individual posts.  This privacy granularity comes at a price according to the New York Times:

By default, all your messages on Facebook will soon be naked visible to the world. The company is starting by rolling out the feature to people who had already set their profiles as public, but it will come to everyone soon.

People like walled gardens. Taking a term from Seth Godin, interacting with just the handpicked few forms a tribe.

If sunlight is the best disinfectant, then social networking on Facebook will die should it be exposed to the world (or too hard to remain private). The most common criticism of blogging is the whole world is in your business. People like the faux-protection of participating online where Google cannot archive it for posterity. This is why Facebook experienced such explosive growth.

Hopefully users will be able to deal with keeping everything as private as they like. Otherwise, we’ll be looking for another walled garden. Maybe I’ll even end up back on my private Twitter account?
