An offhand Twitter comment reminded me of Google+ and its Circles feature, which allows you to very easily separate friends into different groups and post different updates to particular groups. Facebook has similar capacity where you can put your friends in categories.
Here’s an idea: Facebook should start making amends by implementing a feature where anyone can randomly assign their friends to two categories: “treatment” and “control”, or “A” and “B”. Then anyone can try different status updates and see how they differ in the responses and “likes” that you get. You could either reshuffle after each status updates, or conduct entirely alternate personas and lives. Point is, why should Facebook get to have all the fun? WE CAN ALL DO CREEPY EXPERIMENTS AND MANIPULATE ONE ANOTHER.
(I’m being facetious. Well, actually, it would be cool if— No, that’s me being facetious again.)
