I would prefer Bittrex first over polo because we should stay clear of the others for the time being...considering how...different NFD is in its inception and very wide distribution. We don't want to jump into polo and get "oh look another one", when this coin is very different (read: not sketchy), nor do I have any interest in "competing" with the other sketchy ones I won't name.

BTER is a nice option as well, they already have a thriving NXT market and I bet a lot of people there would want some NFD as well...
