This is definitely an interesting idea. If you can build it (and that's a big if), then it will almost certainly have a market, since it is solving a very specific problem that a lot of people have and want to solve. The biggest question is, can you build something that works well? I like the idea of relying on HN comments to try and decide whether the article is worth reading, and I can see the potential for adding more and more "opinion" sites later on to cover more articles on the web. I'm not convinced that it will actually help, but it should be possible to build this just for HN and see whether it helps or not. In any case, great idea. I really hope you make this work!
