Markdown has been a formatting option for developers and widely used especially since Github became popular. .md files support this format. Personally I am comfortable with the formatting but it is the drafts that is worrisome for me.

Currenlty the team of Steem is concentrating more on the base blockchain. Steemit.com was more like an interface until others came out with better interfaces. I am not sure if Steem INC would spend lot of resources on this as they have other priorities. May be they can more people from community into this initiative so tht they don't need to burn lot of resources.
