Go to your wall. On the left hand side of the page under Intro, it should say "Followed by #? people".  If you click on it, you will see all those following you. Mine currently says I am "Followed by 37 people" and many of those I do not know. Some Islamic sounding names, probably because I do post anti-Islam stuff from time to time. Maybe the others just like my political posts. Who knows. Btw, I also tried the other method of searching and it didn't work.
