Technically, both the seat and lid should be closed before each flush. This reduces the scattering of fecal particles and other bacteria around, helps prevent objects from accidentally falling in the bowl, and provides a neater overall appearance to the room. Plus it has the added benefit of circumventing the whole seat up vs. seat down debate.
