The Internet Often Increases the Diversity of One's Social Networks

The Internet often increases the diversity of one's social networks beyond face-to-face interactions,which tend to limit social networks due to race,gender,and social status.However,the Internet can also limit the diversity of social networks for some people because:

A) it is easy to find out someone's gender,race,or social status on the Internet
B) there is a "digital divide" in which low-income and ethnic minorities are less likely to have access to the Internet
C) there are many racist and sexist groups that use the Internet to organize
D) studies show that people tend to form networks on the Internet based on race,gender,and class instead of shared interests
