Systems and methods automatically define relationships in a social networking environment. A discussion thread of a social networking environment is monitored for comments. When a comment is received to the discussion thread from a first user of the social networking environment, a relationship of the social networking environment is automatically defined between the first user and a second user associated with the discussion thread based on the receipt of the first comment from the first user. The automatically-defined relationship information is used to format news feeds with updates regarding activities taken in the social networking environment by related users.
