Overall FINDINGS: Reddit is a news aggregator site, but is most active when the information feedback cycle doesn't exit the platform itself, (i.e. when the sources are mainly from reddit) Attention span of Reddit posts only lasts as long as there can be explicit Redditor influence over the course of the event
