I guess my point is that science is large enough and has enough history that it doesn't need the 24 hour news cycle to be interesting. In the sense that what you already know is news to most people, you can stay interesting without getting a scoop.
I tried following ScienceDaily with an RSS feed a while back and it was just too much. A fire hose of articles and little organization.
One thing I wonder is why there isn't a resource like HN outside of this area. I suspect that people aren't doing as much writing to understand themselves in other fields, and at the same time, they are afraid to discuss preliminary results publicly.
