I'm not sure it's necessary. Think about it. Atheism is lack of belief in deities, right? So if nobody believed in deities there wouldn't be any such thing as atheism. Atheism in and of itself isn't really a topic of conversation, but a lack of one. Our entire reason for talking about it in the first place is that there are religions in existence that wind up putting us into a minority status, sometimes denied equal rights, other times persecuted. Therefore, in my mind, everything that there is to talk about atheism is reactionary to topics that come up in religion, philosophy, etc. We sort of have to wait for there to be a belief in a god that affects us before we have something to talk about regarding our lack of beliefs. Anything we talk about can be discussed from an atheist perspective, like science, but does not require discussion of an atheist perspective.
That's just my .02
