This paper explores new approaches and methods to characterize post and citation dynamics in different blog communities. In particular, evolution of post popularity over time is studied, as well as information spreading cascades. This methodology goes beyond traditional approaches by defining classes of dynamic behaviors based on topological features of the post network, and by investigating the impact of topical communities on post popularity dynamics and on information spreading cascades. This methodology has been applied to a corpus of active French blogs monitored during 4 months.
