Maybe it is one way to go.

But I had a similar though with newspapers. There are quite a few I like. Yet, there are more articles in one that I can read - especially when I want to have other sources as well. So yeah, if there were only a handful of good blogs, it would be the case. But there is a long tail of interesting stuff there.

Anyway, even for the Hacker News, I would like to filter a bit, so to have feed like the hackernewsletter (which I like a lot), but profiled more to my tastes.
