This paper presents a formative evaluation of an interface for inspecting microblog content. This novel interface introduces filters by communities, and network structure, as well as ranking of tweets. It aims to improving content discovery, while maintaining content relevance and sense of user control. Participants in the US and the UK interacted with the interface in semi-structured interview...

Social network sites (SNS) are becoming increasingly important, both for individuals and organizations. These systems have affected social and cultural activities, work practices, and in particular the ways in which we discover, share and consume information goods. The functionality of SNS is emergent, shaped by user appropriation choices. In this paper, affordances are proposed as a way to und...
