I'm a big fan of brainstorming like this, but I tend to err on the side of simplicity. This idea ranks higher in complexity than I'd like to see as a first cut at a solution.

How big is this problem? I haven't yet traded in this market. I've traded in Bitshares markets extensively and have been part of those conversations about liquidity, so I imagine this might be similar.

Would this problem be expected to go away with larger adoption of Steemit, in general?
