如果最初的Facebook只是（一段对话）的开头5分钟，那么我今天所展的则是这段对话余下的部分，也就是长达几个小时的深入、精彩的交流；而下一步的流媒体功能（stream）则可以将呈现的对话时长延长到15小时。

If the original Facebook was the first five minutes [of a conversation] and the stream was the next 15, what I want to show you today is the rest--the next few hours of a deep engaging conversation.
