I use QuiteRSS and group feeds into folder by their relative signal-to-noise ratio (as determined by me). It works well enough: when I only want to see content from sources related to iOS/Android development I only look at that folder; when I have more time I look at the other ones. Mark everything as read when I am done scanning news. Later, rinse, repeat.
