I really like the CSI feature - it made me think forward:
This kind of indicator could be used improve Steem in a protocol change in order to be considered in the calculation of post reward for each vote.

For example if the indicator is positive, it would have positive impact on your voting value. The same around when the indicator is negative, it would have penality for voting value from the voter.

In case the CSI is not exploitable, it would benefit the whole Steem ecosystem and would achieve a much more fair reward distribution for content creators.
