That definitely would have been much more interesting. Generate a few accounts. consistently cause the algorithm to think you are Red vs Blue (via Likes, Profile tweaks, Posts from specific sources like Mother Jones vs Instapundit/Drudge) and then see how they start to diverge. Reminds me of the Like-Everything experiment Wired tried. a while back. Much more interesting to see how it slowly moved toward what the Facebook thought was the local maxima.

Unfortunately, without knowledge of Facebook's algorithms, it might be a bit difficult. For example, I'm sure a decent chunk depends on your social network and what they are posting and that's much harder to simulate. EDIT: I still find this illuminating. I am subscribed to two feeds, one Far Left and one Far Right, and it's always fascinating to look at them and how little they overlap. They pull from completely different sources and focus and nitpick and the craziest things about each other. Even when they cover the exact same story, they contextualize it completely differently with insinuated comments and bylines. So, it's true it's not purely organic of real Facebook feeds. And as a result doesn't get to the heart of the criticism of Facebook generating echo chambers. However, it is a good exercise of showing how this might look and how jarring it can be to compare them.
