Reddit organizes conversation around communities
Reddit started in 2005 as a user-powered forum and developed a model centered on communities and volunteer moderation.
Context and provenance
In prepared congressional remarks, Reddit co-founder Steve Huffman described the site's 2005 beginning as a forum for finding news and interesting material. He contrasted its organization around communities with services organized primarily around individuals. The same account explains several layers of participation: company-wide policies, community rules enforced by volunteer moderators, and votes from individual users. These are the company's description of its governance, rather than independent proof that every community works well. They nevertheless identify important parts of the product's structure. A Reddit thread is shaped not only by its author, but also by the community where it appears and the decisions determining what remains visible.
Why it matters
Community structure becomes part of the content's meaning. To understand an archived discussion, readers need its local rules and moderation context as well as its words and votes.
