There's no point in fighting concrete, and I really don't know why you doing that. Blurt currently has all the solutions you're talking about, plus an increasingly active community and mechanisms that reward voting for content and also for content over time, which eliminates the greed factor because the voter then gains nothing.
It's incomprehensible to me that people like you want to keep digging in here instead of simply switching to Blurt.
You think Hive is a more mature and developed platform, but the truth is that 90% of all these advanced tools are open source and could be ported to Blurt in a few months. Markets and volumes, in turn, are a matter of user numbers. The more people selling and trading, the higher the volume and the more opportunities for new exchange platforms.
It's just a matter of understanding that instead of trying to smash your head into concrete, it's worth simply going around the wall ;]
RE: If You Were To Build Hive From Scratch Again What Would The Community Want to Do Differently?
