A pretty much needed thing are tools to prevent reward pool raping. I would encourage minnows to help steemit themselves by having a post for them to read about that topic and consider to become kind of steemit guards. If they are aware of those things right from the beginning of joining steemit, they could improve and establish Steemit as a social community with real value which it is not in many places. Of course there should be some encouragement for those minnows, some kind of curation, that is rewarding such efforts. This could be interesting for minnows that are not knowing what else to do on the platform.
