In addition to being a platform to show what one has to offer, Steemit is also a platform where one can show who they are.
This is a place where you can say, "This is me! This is who I am/was, and this is how I lived my life; these are the things I saw that interested me and how I reacted to them."
Authors post their writing so it can be shared with others, so why not share with others who you think you are? The blockchain not only offers a free repository to contain information about ourselves, but also gives a way to meet others anywhere In the world and learn about their lives and learn to see them as real individuals.
Steemit can be a lot of things to a lot of people, and none of the uses infringe upon the others...except for the rewards pool-raiding bots, but even those will not squelch creativity.
this is one of the main draw cards I think as people start to realise the importance and (rarity) of uncensored expression.
