AMA with Bungie's Christopher Barrett upcoming (Destiny)
I hang out on /r/worldbuilding sometimes, and I noticed in their list of queued AMAs*, Christopher Barrett (the art director on Destiny) is set for an indefinite date sometime after May 22. So if you have questions about the world building side of Destiny, it might pay off to keep an eye on that schedule.
*that's Ask Me Anything for you non-reddit folks
