The most traditional definition of a human community was a group of people larger than a family that interact. A community may include people who have at least one common point of interest. In the past, community members lived relatively close to one another in one geographical location: in the same village, town, or city. Nowadays, however, the word community can mean a national, an international, or even an online group of interacting individuals. Therefore, a new definition of community might be a group of people that recognize that they have something in common.
