If you wonder why this is only listed on 2 exchanges, why the site is not working and why the dev is not answering, take a look at his profile, he is not active since the begining of March 2017. So this project is dead like a rock for a long time unfortunately.
This may be a bit of a noob question, but now what? i.e.: Could/would someone or a group of people 'simply' 'take over' the project and keep it going? Absorb it and keep rolling? Getting even a volunteer lead Dev, pump in a bit of marketing, seems like this could potentially bring it back to life. What are your thoughts?
