IMO, the curation guidelines should also include the users engagement and behavior within the Steemit environment on the Musing.io platform. That is, users should be incentivized for upvoting or commenting on the questions or answers they deemed useful. The responsibility of curation should not be falling on the shoulder of the selected curators only, instead the community should play a role as well.

Maybe, Musing.io could use a little reference from the Account Based Voting (ABV2.0) from SteemHunt which implemented the so-called Hunter Level.
