That's what I would definitely suggest. If you want to have a healthy platplatform and are a whale, then just look for the top manual curators in every huge 'tag-group' and delegate some sp (if you're greedy, then demand some form of repayment)

This way the steempower and its distribution can scale way easier then you curating manually and you have another layer (the manual curators) doing this. The only ticky part is to find the great curators and I thing someone should start building an intelligent stats-tracker to achieve that.

Kind regards Mister Witness! (:
