“Ethnography, an approach for studying everyday life as lived by groups of people, provides powerful resources for the study of the cultures of virtual worlds. As ethnographers, what interests us about virtual worlds is not what is extraordinary about them, but what is ordinary. We are intrigued not only by the individuals in a group, but by the sum of the parts. We aim to study virtual worlds as valid venues for cultural practice, seeking to understand both how they resemble and how they differ from other forms of culture. We do this by immersing our embodied selves within the cultures of interest, even when that embodiment is in the form of an avatar, the representation of self in these spaces. The goal of this handbook is to provide ethnographers with a practical set of tools and approaches for conducting successful fieldwork in virtual worlds”
