Good point. I think it would be wise to at some point encourage the high tier delegation receivers to have a public document explaining its curation policy and voting guidelines. At least I am preparing this for SteemPress. Then both the committee and the community can read what plans the receiver has for using their delegation, how they intend to do it, and then hold them to account accordingly and/or provide feedback on how the voting guidelines could be more effective or the policy more positive.
