The article’s aims are twofold – to investigate the potentials and limitations of online ethnography and to delineate the discursive dynamics of Indian technoscientific cultures as evident on a nuclear township’s online social network site. Technoscientific cultures of the south cannot be simply seen through a postcolonial lens in terms of north–south tensions over the global political economy or merely through a developmentalist paradigm. There are more complex and illuminating territories with which to appreciate such cultures through the eyes of their protagonists. I note that while Weberian trends towards bureaucratisation are discernible among Indian nuclear technocrats, there is also a considerable counter-narrative in which there is a ‘reconstitution of the cultural’ that demonstrates a strong proclivity towards reinventing particular strains of religio-cultural discourse. I illustrate these dynamics by providing an ‘e-thnography’ of the material posted on the social network site set up in 2010 by scientists who live in a nuclear township in Mumbai. In so doing, I diverge from liberal human-centric understandings of the context of media technologies to consider critical junctures where the subject interfaces with informational technologies in such a manner that notions of the centred and corporeal self dissipate, but traces of his or her embodied self remain.
