A similar project popped up 6 months ago, "HN for research papers", I found it interesting as a physicist turned software developer, and still casually interested in science. It had traffic for a couple of hours and now the site is not even up.

There's also a "HN for Golang", that site also has practically no traffic and discussions.
The challenge with all these sites is always the same, how can you attract enough people so that there's a healthy discussion on at least some of the top items and how will you make people's attention worth it over HN / Reddit / Twitter.
So far, only seen it working out partly for lobste.rs, there, at least there's some discussion, but TBH I still ask myself how is that better than just going to HN or even Reddit, as the conversation is practically the same as here.
