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 users popularity with respect to the prototypical behaviour the user demonstrates.
We perform this analysis on a selection of discussion forums (subreddits)
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.
