title = "Here, have an upvote: Communication behaviour and karma on Reddit",
abstract = "In this paper we cluster users of discussion forums into behavioural roles based on features derived from their egocentric reply-graphs. We then analyse the user's popularity with respect to the prototypical behaviour the user demonstrates. We perform this analysis on a selection of discussion forums ({"}subred-dits{"}) from the popular social news aggregation website Reddit.com and show that while many of the forums exhibit similar compositions in user behaviour, different behavioural roles yield different distributions of popularity ({"}karma{"}) among the community. We uncover a small core of highly active users who play an instrumental role in initiating and sustaining communication throughout each community.",
