I agree with this completely. I would add that the "Lists" feature changed the way that I use Twitter for the better. I now have lists for each of my core interests and & topics -- Economics, Aviation, San Francisco, etc. -- and turn to those when I'm in the mood for specific information relevant to those areas. It helps that all of the tweets are in the context of a specific topic, versus the normal feed, where everything is reverse chronological and jumps from topic to topic.
