I don't think this is a problem. Some things are of different interest to different audiences. HN is one audience, and that's where its strength is. If you want a system that supports multiple audiences, why not use Reddit?
I agree with you. The only curious thing here is I feel the project might be a bit interesting for HN as well. HN and /r/programming should not be that different...
When it's first shown on Reddit there were tens of visitors in the first few minutes, far more than the case for HN.
