In contrast to the common view of blogging as a highly narcissistic activity, this study explicates how blogging is a communal activity and the emergence of a collective identity which drives collective action. 41 interviews with activist and nonactivist bloggers revealed that shared consciousness, distinctive blogging practices, and the articulation of a common adversary contribute to the development of a collective identity. Furthermore, identity multiplexity points to the emergence of “individualized collectiveness,” which extends beyond networked individualism and is reinforced by offline participation in activism and pre‐existing social ties with other activists.
