Thank you for your observations.
We think once we get the users here and if there are many more interesting projects than this one for them then we are sure they will interact. It will depend what steem will have.
People can be paid directly without asking them to comment here with bit of involved coding. Which we can explore if we see it is gaining momentum.
But major point here to show these links is to be verifiable on blockchain for any audit later on by any party that may have stake in the system.
Another point we are assuming is when SMTs are enabled then the posts like ours will only be visible to only our community.
