在一个社交网络里，一旦现有用户的大部分联系人都已经加入同一网络，那么新加入用户给现有用户带来的价值就会呈现高原现象。
In a social network, the value for existing users of a new user joining the network plateaus once users have most of their own contacts in that network.
基本思路是，一个个人在特定主题上权威度，加上他在该主题上的网络兴趣和权威度，结果就是等同该消费者的价值。
The basic idea being that an individual's authority on specific topics plus their network's interest and authority on the topic, results in a value of reaching that user.
你提供的价值包括一个动态环境，在这里成员可以互动并引领话题，参与他们在公共网络上无法找到的活动，并获得认可。
Providing value includes a dynamic environment where members interact and drive conversation, participate in activity they can't find on general social networks, and receive acknowledgment.
