What makes your audience a group or a community?
Community and group are words that are often used interchangeably, but there is a difference between the two. A group can be defined as several people who share a common interest or goal.
Those people may be organized in any way and still be considered a group. In everyday life, groups may be based on age, race, gender, religion, education level, or any other factor which brings people together because they have something in common.
