I think (2nd attempt) at getting it on Yobit is priority. It's quite a popular exchange and works very well.
Another coin that I followed for years also lost Crypsty but got on Yobit and that helped it tremendously.

Getting on Bitt/Polo is much harder unless you have internal connections or pay a lot of BTC as downpayment.
I do agree that coin/community development is important but a nicer trading exchange definitely doesn't hurt.

my 2 CSC worth.
