We also see wikis as being communities. They are also part of communities around a topic, a community that can also include news articles and Discussions.

Communities here are a place where people can express their fandom in whatever ways they want. Some people do it through wiki editing, some people do it through conversations on Discussions, some people do it by writing articles, and more. The opportunities for where and how to contribute are growing, and those contributions are all in some way an expression of a person's passion and fandom for a topic.
