Nice job @kevinwong. I think it's a smart idea for the top steemers to diversify out when giving out tips. If certain tags are not being engaged then it will drive steemers away. When you distribute the wealth to other factions it will keep them engaged in the community and the whole ecosystem will be rewarded.
Yup I suspect it'd take time though.. maybe a pop of at least 1 million people to get niches properly filled (both supply and demand). The screen size remains the same, but users are growing exponentially..
