Looks like another shit coin copy and paste to me. Market built-in to the protocol? Why? What possible benefit is there over running an external market? Website is superficial and there is no real innovation. I'll pass on this one.
The benefit of P2P marketplaces has been discussed for sometime now in the Bitcoin community, especially after the failings of MarketPlaces like the Silk Road. External marketplaces holding onto funds due to escrow run a high risk of being compromised security wise, and a P2P market place fixes this. Just a note.
