We explore how self-injurers, a group of deviants who primarily were loners, now use the Internet to form subcultural and collegial relations. Drawing on virtual participant-observation in cyber self-injury groups, over eighty face-to-face and telephone in-depth interviews, and over ten thousand e-mail postings to groups and bulletin boards, we describe and analyze the online subcultures of self-injurers.

We further analyze these individuals and their interactions to compare and contrast the venues that they use, the communities and relationships that they form, and their relation to real life. We contribute to symbolic interactionism through our social constructionist stance toward the creation of virtual communities and relationships, our focus on identity and stigma, our view of social organization as grounded in the panoply of human interpersonal relationships, our contrast of the competing reality claims posed by virtual as opposed to the solid world, and our discussion of the modern versus postmodern self.The cyber world represents a new frontier, one that extends what has often been colloquially referred to as the fourth and fifth dimensions: time and space. Just as Melbin (1978) analyzed the night as a temporal frontier, the cyber world is a domain that occurs in a new form of space both "out there" and "in here"; it is simultaneously public and social, while remaining private and solitary. It is a postmodern form of space, created by technology and populated by disembodied people in a virtual universe detached from the physical locations known as place. These spaces are
