Nobody here is creating groundbreaking research untouched by the human mind. Everybody is just re-jiggling information in their own style in their own order. As in, I might take already-known knowledge from 17 different sources and combine them into one, thus making a unique post with my own voice in my own direction. None of it is stuff nobody knew though.
What is to be considered also is that steemit has people from all over the world, who share different knowledge and experiences from what you're typically useful, so it's worth more than ever sharing one's views
