Do you imagine B&C will list the trading pairs with more trading volume or take a more open arms approach with alts seeking to be listed? / Who is your target market as far as customers go?

How do you think the trading experience will compare to that of a centralized exchange?  I have seen the 10 trades a second ceiling in the paper, but that doesn't necessarily mean actions will be completed in 1/10th of a second, does it?  What stops anyone from front running a trade or action before it is 'confirmed' on the blockchain?
