People like to show approval. There should be a LIKE flag and count as well as a vote flag and count. Steemers need to be educated further to understand the voting mechanism and reward but provided with the means to express approval. Both voting and approval could feed into the reputation algo. This may help to stem swarm voting, but does nothing to improve the rate and breadth of steem power distribution. The whales/dolphins need to gift/seed some stake rather than lend it....though how you accomplish that in a fair way, I don't know.
