In the first Antho iteration, privacy was a difficult concept to design, because the site's user-generated content was much more personal than any other social media site at the time, and thus likely to be more sensitive. The kind of material posted was also likely to be much more relevant to just a small circle of close friends and family members.
To accommodate this level of intimacy, the first iteration allowed for “kinships.” Kinships are invitation-initiated, permission-granted user relationships very similar to Facebook friendships. Only users designated as a given user’s “kin” could view that given user’s anthology.*
Users could, however, write stories for others that are not their kin, with or without first requesting those users to be their kin. The non-kin user-author would be able to view his post on the user-subject’s anthology, but that would be the extent of his visibility of the user-subject’s anthology, unless a kinship is established.
*There was internal debate over whether users should be able to view stories about their kin written by users who were not their kin, or written by their kin about users who were not their kin. In the end, for the purpose of establishing a more visible culture, we opted for greater transparency, and allowed users to view stories written by and about their kin, whether or not the respective subjects or authors were also kin.
