Hello, is there a way to view a list with all of the people I follow, who haven't followed me back? Thank you in advance.
I agree, twitter karma is a good app. You can view the people who you follow and follows you back, those who only follow you, and the ones you are following but don't follow you back. It also indicates the time when these persons last logged in twitter so you'll know who are still active.
I use friendorfollow.com It breaks your friends list up into people you follow only, people who follow you only, and mutual followers.
I would suggest a best tool that allows you to follow or unfollow 40 users at once. its Tweepi - A geeky Twitter tool you can easily flush the unfollowers and reciprocate the followers
