Nice post.Firstly Steemit should make resteeming reversible.
Secondly Steemit should look for a way to reward minnows with quality post better.@screenname identifies posts that are undervalued,i believe they should go a step further by rewarding such posts.
Thirdly,you could set up an unbiased curation team to help noobs hone their skills by identifying their weakness,making neccessary recomendations in order to improve the community.Stay blessed.
