I prefer AP style most of the time because readers are used to it (most print publications follow AP Stylebook rules). But we're free to develop our own style; I'd argue that, in some instances, we should.
Are we going to say "Web site," which is AP style, for example, or are we going to use the increasingly common "website"? And the AP Stylebook calls it "e-mail," but when was that last time you or anyone you know actually hyphenated that particular word?
And so on.
Maybe I'll start a Basecamp project on this. In the meantime, feel free to comment here or email me with your suggestions for how Discover Mediaworks can best say it with style.
