I use Elfeed for Emacs, as just one small part of Emacs’s slow conquest of other programs on my computer. Before that, I used Liferea, which is a nice standalone feed reader.

Elfeed lets me assign each feed in my list different tags, so I can do basic filtering for what I want to read at any given time. I generally avoid subscribing to any high-density feeds like news sites. I prefer to have maybe a dozen or so links per day that definitely interest me.

I use morss.it to fetch the full text from feeds that only provide a brief summary.
