My questions were the following:
Q: If the power of Adonalsium was intentionally shattered (perhaps to keep it safe), why did some of the shards stay together in one place (like on Sel, Scadrial, and Roshar)? Wouldn't it have been safer to split up?
Brandon: The relationships of the holders of the shards influenced where they went (after the Shattering) more than anything.
Follow Up Q: So friends or lovers stayed together?
Brandon: Well, sure, but the relationships could have been more than just that, but it could have been like a business partnership or something.
Follow Up Q: So have any other shards intentionally allied themselves to one another for various reasons (since the Shattering)?
Brandon: RAFO!
Follow Up Q: What can you tell me about Skai/Dominion's relationship with Aona/Devotion and why they decided to stay together in going to Sel?
Brandon: RAFO!
Q: Have any other shards ever bonded together like Harmony (Preservation and Ruin)?
Brandon: RAFO. You get a card! =)
Q: I have a feeling that the threat of Odium is really a red herring to a greater evil in the Cosmere, perhaps one we're starting to see in BoM?
Brandon: (Smiling with a pause) You'll just have to RAFO!

This was such a cool experience and I'm so amazed that an author would take this kind of time to ask we his fans for questions about his work. I love that even when he wouldn't really answer my questions he still acknowledged my interest with a RAFO card, which I think is the ultimate way to respect fans while still protecting the secrets!
