This is an interesting article that a friend of mine found. It's mostly concerned with linguistics, but there's some interesting cultural material there.
On another note, it would be great if people could check out the omnitheism.com site. Martin's revamped it and is trying to build a more communal atmosphere, and I'm all for a communal atmosphere.
I've also been trying to get the MySpace Omnitheism group to look at our work here, so it'd be awesome if we can build bridges there as well.
