So, I'm not really a crypto hawk and watch every alt coin currency out there, but what separates this Pandacoin from the one already listed on MintPal?

The one that's already listed is Wolong's scam coin which has a 3% premine.
The one that's currently on the voting page is the fair coin with 0% premine.
Bigvern made that twitter joke about panda been added to crapsty
went something like this
we have added PANDA,PAND,PANDAA,PND,PANDA,PAND,PANDAA,PND
and i think he might have added a few more pandacoins into the mix
