The top secret labs at Facebook are in overtime right now: another experimental feature has been spotted in the wild. Soon we might be commenting on comments.
As it stands now, the best way to talk to someone else within a status comment thread (mouthful!) is to tag them in your reply. But according to Facebook, which confirmed the new feature to Mashable, we might soon be able to reply directly underneath someone, old-school blog style. This will make it a lot easier to see who's talking to whom, but could also twist our Facebook statuses into complicated message boards instead of just... statuses. It also opens a conceptual future for Liking a Like, which would in turn open a wormhole into hell. [Mashable]
