Okay, so I've taped a few shows, can't be happier with how they have all come out. As I was looking through rig photos, I have noticed this in many of the pictures:
Many of you run your mics "cris-crossed."
Or, something like this too: (last picture)

What's the advantage of this? Anything?
Sorry for the noob-age.
Cheers.
that's x/y. you can have them @ 90deg or more/less depending on what you're after. typically you'll pull the image in a bit (tighter) with this config, over din, din-a, ortf... but it depends on factors such as distance from the source/dfc, and the room. i like x/y a lot as it tends to place the instruments more precisely.
the dpa university link is a good basic tutorial. the main thing with cards, especially, is that you do not want the diaphram pointed directly at the source = brassy and harsh. so you want them off axis at least 90 deg... people disagree somewhat about this, but then what would we have to talk about?
what you are trying to do with these techniques is recreate the psycho-illusion of stereo. think about where your ears are (physically) when you perceive stereo.
