Yeah, I'm totally on for taking the Black out of the black market (except when it involves nice shiny black things), it's an early objective for the Steem Co-Op - peer to peer marketplace.

Remember me talking about escrow? I believe actually it's implemented on the Steem blockchain now as a multisig transaction. @good-karma also clearly knows where it's at for advancing this platform, he's working on a marketplace too. Maybe I need to talk to him.
That's good news! I know Feruz is working very hard and he seems to be making great progress all the time. It's very inspiring to see! See if you can get a hold on him.
