You're right, I'm recently in steemit and I still have to know projects that use alternative interfaces.

For now I refer only to the main steemit platform. Both from the interface point of view and from the point of view of technical functionalities (for roles). In this sense, steemit does not facilitate the reader (the one who has no profit goal) to use this platform (registration, wallet, blockchain, and everything else). Furthermore, the platform is not easy to use to store interesting but old content, etc. (I hope soon there will be new functions in this sense). The editorial business is normally scalable while steemit rewards the content only in the first week (this is good in a social network perspective).
If I am developing professional publishing projects I will have to go where the reader is, I have no alternative to this. And steemit still needs to grow a lot in this sense.
All these things that do not help.

However, I realize my lack of knowledge of steemit. So most likely you can give me some suggestions.
