That would drive me crazy. RSS might not be the perfect technology, but for someone like me, who likes to skim headlines and brief summaries throughout the day, it's a great way to keep everything organized. I don't want all of my RSS feed to be social.
IMO RSS is one of the backbones of the social net. There are a lot of people out there that pull content into the social networks from their rss stream.
There is also this: From my experience, social networks as they exist today are totally useless for keeping up with a large number of information sources. It is just impossible to keep things sorted. Maybe I'm doing it wrong?
