Interesting thought. I'm torn because on one hand I agree with you, had incredible value of mining people's twitter likes as a way of truly sampling other people's feeds (often times find them to be better quality and more honest than retweets).

On the other hand - personally subscribe to a very, very wide variety of RSS feeds ... some heterodox enough in opinions that I would be instantly canceled / run out of other social zones. So there's a very real sense of protection in RSS feed privacy that's a huge plus there, and would never want to give up.
