I think you're absolutely right about the quality of comments on steemit. I am new to steemit but am used to the sorts of high quality discussions you see in niche internet communities where people with real knowledge share their experiences. But on steemit it's all about the money and the followers and "playing the game". I was shocked at how hollow the comments are on steemit with everyone being all nice and friendly without engaging in real dialectic for fear of losing money and followers.
