Networks are always growing, little by little, node by node. They don’t stay the same size.

Network nodes link with one another, and more likely linking with popular posts than old posts.

this explain the point above. Producers are more likely to cast popular actors than others, simply because they gain more attractions from viewers and fans. This contrast the point when Rich get richer.
Its the same with the employing process. The one with impressive experiences in areas get the job , while the fresh new one don’t.

this is twisted.

Overall, its all about preferential attachment. The one with more impressive links to the right areas will always comes first.
