I'm all for the idea as well.
An Escrow based exchange website dedicated to GoldCoin, the prime example being 'Localbitcoins', would allow an extra platform for transactions, and it would cut out the middleman of having to buy the Bitcoin to begin with. I don't think many (if any) of the other alts have anything like it either. Also, adding the feature of making it possible to trade goods/(services?), probably at a later date if this goes ahead, could bring more people into GLD.
What do you guys think?
