The biggest challenge is finding these quality posts in the 'new' feed. :) My current ratio is 20:1.
Downside: Time-consuming --- Upside: Better Content in Steemit in the near future! :D
My rules:
Flag for content that seemed to be made by a bot (or run through Google Translate!)
Mute for Authors who post in Languages I cannot understand
Mute authors who share content I'm not likely to engage in
Comment on posts or engage in comments. :) Well...if I have something of value to offer.
