The cohomology of $\mathcal{M}_{0,n}$ as an FI-module
  In this paper we revisit the cohomology groups of the moduli space of $n$-pointed curves of genus zero using the FI-module perspective introduced by Church-Ellenberg-Farb. We recover known results about the corresponding representations of the symmetric group.
