How do you pronounce XNA?
Is it X-N-A
or
is it Xee-na?
Is it X-N-A
or
is it Xee-na?
I think the answer depends on how badly one wants to get punched in the head by his or her fellow developers... :P
Since I value my cranium, I tend to stick with X-N-A. But if you're looking to raise the ire of your buddies, don't hesitate to go with Xena occasionally. :)
