recently hacker news simply replaced my rss reader. if there is something new that i may be interested in, i'm sure it will front-page here, so I let other people do the skimming for me.
On a related note that is my approach on Twitter as well. I try to follow interesting people and if they are talking about a common topic or link it is probably worth reading.
Sorry for the plug but that is what we try to do with Cadmus (http://thecadmus.com). You give us your Twitter, RSS Feeds, FriendFeed and we will find the top articles your friends are talking about.
