I think its just a case of user organization/finding good sources ... I was subscribed to techcrunch/engadget etc but I found that because of the high volume of stuff they pump out that I didn't read them at all ... so I got rid of all of them and started using the HN top 20/50 RSS feed that someone made a few weeks ago.
I also have my feeds organized into folders, so that the more frequently updating but news worthy stuff is in one folder and the others are other places ... depending on the time I have I go through them in a particular order and it works very well.
But yes, the truth is that sites that create RSS feeds need to be a bit more picky about what they publish ... especialy since they practice that same self restraint in publishing things to facebook, if they have a presence there
