Subreddit
Subreddits (officially called communities) are user-created areas of interest where discussions on Reddit are organized. Each subreddit is typically devoted to a specific topic or theme. Subreddit names begin with "r/"; for instance, "r/science" is a community devoted to discussing scientific publications, while "r/gaming" is a community devoted to discussing video games and "r/worldnews" is for posting news articles from around the world.
In a 2014 interview with Memeburn, Erik Martin, then the general manager of Reddit, remarked that their "approach is to give the community moderators or curators as much control as possible so that they can shape and cultivate the type of communities they want".[1] Subreddits often use themed variants of Reddit's alien mascot, Snoo, in the visual styling of their communities.
