Recently i had an interesting discus with some Steemers to optimize Steemit.com. Here are some suggestions:
Addition of another language
Steemit.com should translate in different languages.
Counter
This shows how many requests were made to your post
Notification
When a visitor comments on your post, follows or replies you will receive a comment notification
Each Steemers shall receive his own steemit e-mail e.g. [email protected]
I hope that will be taken on board.
