I don't mean this to sound snarky, but if a blog doesn't have a good ratio of signal to noise, you just unsubscribe from the feed.

The solution is to be okay with missing some things instead of trying to drink from the firehose.

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.
