I've been trying to get a couple of my artist friends onto Steemit lately (mostly for the steemfollowers refs lol) and it always seems to go the same way: they're obviously down with the concept of getting paid and recognized for what was just a hobby before, but it doesn't take long for them to lose interest. Last chick said it felt like a cult because all the comments (both spam and genuine) were so positive. I realized she was kinda right, a negative comment would at best be non-profitable and at worst drive your rep into the dirt. She also said that on her own page/posts that she felt 'lonely' (on a supposed social media platform lol) which was weird cause I often feel the exact same way.
So what I'm trying to say is 1:0 risk:reward ratio on negative comments prevents people from having genuine discussions and the format makes new people feel ignored and dejected on a social media platform.
I don't know if chainbb is the answer but it's definitley the closest right now imo
