I find the key to RSS is that you need to subscribe to actual content, rather than just a feed. A lot of the stuff on the internet is, frankly, just a barely curated feed of information pushed out a firehose. Unless you feel like you need to, don't subscribe to feeds from news organizations unless you're willing to skim and blast away lots of unread stuff.
Most of that you simply won't read.With RSS, I like subscribing to journals and organizations that publish substantial content (lots of text rather than ads) at steady but not explosive rates. RSS is pure consumption, so if you're using it to "follow a feed" I think you're doing it wrong. Though YMMV, of course.
