On a cosmic scale, light speed is pretty slow, meaning long communication delays even within a single solar system. Sure, if you develop FTL travel then the problem is mitigated somewhat by being able to physically send messages with some kind of traveling communications probe or by people traveling between places, but it's inconvenient and not always possible, and could still be rather 'slow' depending on how much faster than light one can travel.
