This is a great move. What Steemit really needs right now is a diversity of content. I see a lot of great posts about topics like science, gaming, history, fiction etc. - let alone niche topics - go by the wayside for something directly related to Steemit. It'd be wonderful if you replace some of these Steem-centric authors with some great new authors creating diverse content.
It would be great if someone as influential as yourself would support authors creating content for these varied subjects, and in the future, for niche subjects. Only then will the masses adopt Steemit. This is why Readit has been so successful - there's a sub for every little niche.
Keep up the great work, you're a crucial part of making Steemit a diverse blogging platform.
