Reddit allows communities to operate subReddits around particular topics, and following moderator approval, each one is allowed its own wiki, based upon what looks like a , to discuss its rules or create an FAQ. There are over 20,000 subReddits, many of which have a wiki, but few of which are particular active as wikis. They are mostly a method of creating documentation unique to each subReddit in a quick and collaborative manner.
