An affinity space consists of a group of people who are brought together by one common interest. Be it that they are a fan of a particular webcomic or into baking pies, it is a social group formed by an appreciation or love of something else and where relationships can develop between the active people in a group from there.
Examples of an Affinity Space:
Regardless of where an affinity group takes place, the people involved are able to meet and begin developing bonds with others, regardless of age, gender, race or looks.
A more "colorful" example of an affinity space would be the "fandom" of a very popular webcomic, Homestuck. Homestuck provides a great affinity group due to its popularity. The website for the comic (MSPaintAdventures.com) features a forum where fans can discuss current updates, as well as many social groups away from the main website. Fans gather everywhere from finding each other through Tumblr to having real-life meetups with local fans. By being interested in this comic, many people have been able to get to know each other and build everlasting bonds with unexpected friends.
Also, in this particular group, there is no demographic. Fans are of all ages, gender and race.
