First attempt to list something you may comsider to follow me. How our brain develop is quite similar the way we confront social networks.
  1. Cell multiplication and keep replicate ourselves
  2. Differentiation of cell. We try to categorise ourself as unique as possible.
  3. Cells are relocated and align themselves with cell surrounding to form a particular function. We geographically migrate some place fit us.
  4. Cells must establish a functional relation with others cells. We build relationship because of the benefits people can brought to us.
