yes i think the bot curation is very open to failures in the keyword search lists which create a vote action but without the true ability to read and analyze the content in terms of presentation and quality value. Real curation ie an intelligent person that reads articles, i am sure is more efficient and possibly more profitable for whales in the long run. As indeed Steemit,s success as i see it relies very much on the provision and rewarding of quality posts!! upvoted. What is good for Steem is good for us all no doubt !
