The awesome idea for a contest.
Steemit is well known as a crypto social media, it is best in all.
But everything needed few additions, look at my suggestion as follow.

When I try to write diary I really needed a word counter that time, then I confirm the words. But if you take diaries a side, every article will need a word counting service on steemit, so the author will count words easily.
And on steemit vote percent method is very cool, if it will added. Then the author can vote of how much he think the content deserve.
The crypto world is all better with rewarding, SP/SBD is better.
