I never got into RSS readers, but I use Hacker News and Reddit for the purposes Marco is describing. I have Pulse on my phone set up to follow a handful of RSS feeds (Hacker News, The Verge, Daring Fireball, Ars Technica, etc.) so I have an easy way to see what's happening if I have a couple minutes to kill throughout my day.
From the article: The true power of the RSS inbox is keeping you informed of new posts that you probably won’t see linked elsewhere.
I feel like I've been shouting this into the void over the last few days of RSS-related submissions, but RSS is not best suited as a news-discovery paradigm. Aggregators like HN or Reddit serve that purpose. RSS's sweet spot is tracking deeper content on niche sites or topics that don't get swept up in hype mills, and if you're interested in more than two or three blogs or sites like that, RSS is essentially the way to track that content. Being able to share that and discuss with a select group of people was icing on the cake that Google Reader added.
Without seeming overly defensive about it, I feel like everyone who dismisses RSS lately with "that's what HN is for" has never used RSS in the way that many of us find indispensable.
