Facebook provides various social benefits for my participants. However, it also concerns them by making intimacy problematic. In response they develop novel solutions to these problems. I seek to theorise these problems and solutions through mobilising appropriate conceptual frameworks. Three fields already prevalent in SNS scholarship help in this regard: "privacy", "performance", and 'social capital". Each provides a particular way of thinking through these issues. In what follows I tour through literature which explores these frameworks, suggesting points of critical synthesis which will be taken up in the empirical chapters to come.
