Very interesting question, I don't anyway but personally I think curation is the best way forward. Of course the argument is manual curation is a little too much like hard work for investors looking to earn a "passive" income - but using something like steem-auto fanbase you can automatically vote on your favourite content creators and earn from curation rewards.
In an ideal world we would of course all be using our "Proof of Brain" to apply appropriate upvote based on the post quality and then leave a comment - in reality unless you have 24/7 to spend on steemit that is an impossible dream.
It is an impossible dream to do with your own account for sure, this is one of the reasons to support manual curation teams - although you don't make ROI there at all, unless you join the right trail I guess.
I would choose to curate and delegate too - business as usual for me.
