By focusing on diversity of personal networks, I will show the structure and function of diverse networks. My hypothesis is that networks rich in diversity don't always include many bridges. To verify the hypothesis, I examine the relation between bridges and network diversity, then show that the both have no correlation. I find that a network that has many bridges is not diverse.
Diverse networks have the following structure and function. First, diverse networks include many contacts and their structure allows an escape from dependence on a boss. Second, diverse networks function to collect information and allow escaping from network constraints. My findings suggest that diverse networks bring benefits and have no relation to network bridges.
