Find out the people you're following who aren't following you back. (Depending on the number of users in your 'following' and 'followers' lists, this might take a while.)
Just to clear things up, if your profile link is http://soundcloud.com/foo/, type 'foo' into the text box.
UPDATE: You can now search from the URL. Just type http://soundcloud.onloop.net/?q=yourprofilelinkname to search. Also added, share buttons.
