The first thing to understand about gods is that their attention is not only divided, but splintered. Their facets of themselves may not know all that other facets have recently learned.
(This is a fundamental fact about gods, and from mortals it is hidden, for it is the first step on a trail of secrets.)
The second thing to understand about gods is that it is expensive for them to look at the Material from more than the most abstract and predefined of directions. Far more expensive for them to intervene, especially if another god is opposing their intervention.
(This is partially a fundamental fact, and partially stems from bargains that gods must make, shapes into which they must place themselves, to become gods without being destroyed by other gods.)
The third thing to understand about gods is that by far the most common equilibrium of their many conflicting interests, is that all parties involved end up doing nothing to the Material. This saves the energy and intervention budget of all parties.
(It seems likely that somebody or something made that be true, so that a place such as the Prime Material could be. That selector may have been Pharasma, or it may have been something beyond even Her that determined the shape of Her own desires and powers.)
Nethys, for reasons which may soon become clearer, sometimes behaves as an exception to those rules. Otolmens is also something of an exception, in Her own way. She is called goddess by those who lack finer categories, but She is something older than that, something that came into existence along with or shortly after the multiverse.
Compared to intervening on reality, it is energetically cheaper for gods to talk to each other, seeking rare exceptions to the equilibria in which their conflicting wills neutralize. This leaves a cost of attention - but not every such conversation need consume the whole attention of a facet; facets of gods can split off even tinier subfacets to try conversing with other gods' subfacets. Most of those potential conversations never get anywhere, and are discarded; sometimes they lead somewhere interesting, and those possible conversations are then reconsidered by larger facets. You could consider them as hypothetical conversations, in a way, or pseudo-hypotheticals; they do actually happen, but usually not in a way that affects anything.
The pseudohypothetical messages that these splinters of splinters trade between each other are sometimes so small and simple that they approach, not spoken mortal voices, but mortal writing; though they are not, of course, mortal language of any kind.
