为什么社会网络里的“结构洞”能带来信息优势？
Why does a 'structural hole' in a network bring information advantage?
结构洞是两个本不相连群体之间的缺口；占据桥接位置的人能同时获得双方各自没有的信息。这种中介位置带来更早、非冗余的信息，以及对信息流动的控制力。
A structural hole is a gap between two otherwise disconnected groups; whoever bridges it gains access to information from both sides that neither group has. This brokerage position yields earlier, non-redundant information and control over its flow.

为什么网络中的“中心人物”未必是权力最大的人？
Why needn't the most 'central' person in a network hold the most power?
中心度衡量的是连接数量，而非控制力；一个节点可能很“中心”，却只是信息的过路站，缺乏议价权。真正的权力常属于掌控关键资源、把守要害连接或占据战略结构洞的人，而非单纯连线最多者。
Network centrality measures connectivity, not control; a node can be central yet merely a pass-through with little leverage. Real power often lies with those who control key resources, gatekeep critical links, or occupy strategic structural holes—not simply those with the most ties.

什么是“弱关系”的力量（朋友的朋友）？
What is the 'strength of weak ties' (friends of friends)?
社会学家格兰诺维特发现：亲密好友消息往往重叠，而“弱关系”（不太熟的人）反而带来新机会，比如不常联系的朋友介绍的工作。广而浅的联系常比深而窄的更有用。
Sociologist Granovetter found close friends' info overlaps, while 'weak ties' (acquaintances) bring fresh opportunities, like a job from a rarely-contacted friend. Broad shallow links often beat deep narrow ones.

为什么“认识对的人”常常有助于找到工作？
Why does 'knowing the right people' often help find a job?
很多岗位不公开招募，靠熟人推荐更快匹配信任。介绍人用自身名声作担保，招聘方省去筛选成本，求职者也更容易被相信。
Many jobs aren't publicly posted; referrals match trust faster. The referrer stakes their reputation, the employer saves screening cost, and the candidate is easier to trust.
