In this blog post, I take preliminary steps towards outlining the similarities and differences between the concept of “mobile publics” proffered by Aswin Punathambekar (forthcoming) to characterize the fan activism generated in the Indian state of Meghalaya in support of its resident Amit Paul during his participation in the third season of Indian Idol in 2007; and the twin concepts of “flash activism” and “flash fandom” that I informally put forth (http://sites.google.com/site/participatorydemocracyproject/case-studies/rang-de-basanti-and-flash-activism) while describing the case of the 2006 Bollywood film Rang De Basanti’s role in inspiring civic participation to demand justice in the high profile trial following the murder of model Jessica Lall. I will briefly discuss the two concepts in context of the cases they illuminate, before delineating the similarities and differences between them.
