Thanks for the suggestion. I'll find a better color scheme.
The site is curated. I have a script monitoring many sources. Most of what I collect is trash, so I only keep the best each day. When I discover a new blog, I sometimes include links to a few previous posts.
I don't think the community is big enough to ever sustain a HN clone. One was tried a few years ago (quant.ly), but got shut down.
