Hi @ctime, my project will be released as an open-source after the return on investment which may take some time (I think two years) hahaha, and will be done in different parts, the first one the frontend will be the first to be released.

For the moment the main open sources I release are to help developers on Blurt by providing them libraries, connectors to the blockchain...

If you want to make your own frontend I suggest you start with Condenser (you can even start from the one of Steem if you have any doubts) which is written in React (it easier and cheaper to find a React developer than Angular which is the language used for BeBlurt). A large part is already coded, I think you can get away with a few tens of thousands of dollars to adapt it to your vision.

There will be no hot or trending feeds, as you understand it, but suggestions based on different criteria. I am working on an algorithm performing an analysis of each post published in order to obtain non-native data requiring a specific computation. To base only on the reward of a post to evaluate its popularity is not a model that suits me.

For the mute function, it will be present especially since BeBlurt will integrate the communities that are currently being worked on by some dev (including some core-team members) wanting to give the necessary administration tools to the owners of blogs/communities.
