Friend or Follow - Management of Twitter Followers

Friend or Follow is a great tool to find like minded individuals who are currently following you but you are not following them. In the Twitter Universe there is a school of thought that anyone that follows you, you should follow them. I shy away from that mantra because my Twitter stream would easily be clogged up of unimportant information and spam. That is why I use Friend or Follow. This tool separates "People Who Don't Follow Me Back", "People I Don't Follow Back" , and "Mutual Follows". I take a look at those "People I Don't Follow Back" and scan there latest Tweets to see if they are producing insightful information relevant to me before I follow them back. Do you use this tool or a similiar tool to find Followers you are not following?
