Speaking of blockchain business and selling / buying stuff, I wonder if there'll be a Steem based eBay kind of platform one day? F.e you have something collecting dust on one of your shelves that you never really use, and decide to turn it into Steem - just put it up for sale or auction, add information about shipping (if it's in the price or shipping is extra and if you ship worldwide or locally...). I think it'd be pretty awesome.
