"In the context of Usenet discussion forums, Himelboim et al. (2009)
have undertaken a detailed study of new thread creation. They found that
many Usenet forums featured a small group of 'discussion catalysts'
whose seed posts inspired a lot of debate. Interestingly, these users
largely posted stories from elsewhere on the web with little or no
comment - a relatively conservative approach to setting the agenda."
