This seems like a strange thing for Facebook to build. I'm sure I'm missing some grand idea of why Facebook would make this. I just don't see how they get much out of this and how it fits into their mission.
Edit: I missed that this was coming out of NPE (New Product Experiments). Still I'm not sure why this would make sense for FB to run, but it's less odd knowing that it's an experiment.
