We need to set up a system like Open Bazaar for steem. The solutions are open source and out there, it just takes the right team to put it all together for us. Then we could have a decentralized messaging system, profile pages, and marketplace, this should be the roadmap. How hard would it be to clone up OB and get it to work for steem?
If they can simplify the setup and make it easier for the average user to understand and use, I think that could be a great idea. PeerHub already exists as well and accepts Steem. If they can incorporate the PeerHub store into the interface or at least link to it through the wallet function, that would be a great help as well.
Alongside that, they really need to gamify user customization features that others have been mentioning for months - things that can be unlocked as you increase Steem Power and reputation, and virtual items that you can buy in a virtual SteemShop™ or SteemStore™. This can be added directly to our wallets or at least in the drop-down tab at the top right of the browser.
Lots can be done, big and small. So far, we're only seeing the tiny.
