every day millions of people type messages on their computers in order to make small talk, discuss current events, fall in love, or find new friends. These people form virtual communities on the internet. Each virtual community has people with similar interests, ideas, or questions. One community may focus on a health issue, while another may try to make political change. Just like neighbors in small towns, virtual community members may start out talking about one topic and end up talking about another. They may also offer help when a community member needs it.
