I partially agree - I do use RSS to check for sites that publish daily updates (yes, even Hacker News). But even with those, you don't need to overload yourself. Right now I get about ~100 news every day, which is perfectly fine with me. I went away last week, and I was greeted by ~500 news. I was able to skim through those in maybe one hour, so it was fine.
Everytime I feel that my feed reader is overloaded, I write down every site that I follow, and decide about which sites I really care, and which sites i can easily unsubscribe without problems. I also try to remove sites that post the same thing (this happen a lot with news sites).
