Query: Neutral Theory for competing attention in social networks   We used an ecological approach based on a neutral model to study the
competition for attention in an online social network. This novel approach
allow us to analyze some ecological patterns that has also an insightful
meaning in the context of information ecosystem. Specifically, we focus on the
study of patterns related with the persistence of a meme within the network and
the capacity of the system to sustain coexisting memes. Not only are we able of
doing such analysis in an approximated continuum limit, but also we get exact
results of the finite-size discrete system.
