From Valleywag:

In a conversation with GQ, Mark Zuckerberg reveals that he hopes Facebook will one day broadcast its users very emotions. Alex French probes him on this issue in the following exchange:

(12:25 p.m.) Alex: How’s things?
(12:25 p.m.) Mark: There’s this definite evolution happening. Where the first part of the social web was mapping out the social graph. And the second phase is now mapping out the stream of everything that everyone does. All of human consciousness and communication.
(12:29 p.m.) Alex: Imagine if you could broadcast people’s emotions into a feed?
(12:30 p.m.) Mark: I think we’ll get there.
(12:30 p.m.) Alex: So how are you going to map all of human consciousness and communication?(12:30 p.m.) Mark: We don’t map it directly. We give people tools so they can share as much as they want, but increasingly people share more and more things, and there’s this trend toward sharing a greater number of smaller things like status updates, wall posts, mobile photos, etc. A status update can approach being a projection of an emotion.
(12:31 p.m.) Alex: That’s what I use it for.
(12:31 p.m.) Mark: So it’s not so crazy to say that in a few years people will be doing a lot more of that. It takes time for people to be comfortable sharing more and for the social norms to change.
