Twitter is a great service, however it lacks a few things in the user interface department. Some questions that often arises are: Who are you following that’s not following you back? Who’s following you that you’re not following back?

Enter Friend or Follow (FoF). FoF is a cool Twitter service that allows you to individually find out, the answer to the following:

1. Following – people you follow and don’t follow you back
2. Fans – people who follow you that you don’t follow back
3. Friends – people you follow that follow you back

Once you have determined , what you want to do, just click on each user and do what you have to do:) What’s really cool about this Twitter service is that you are required to submit your password to use the service. It is totally free and no registration is required. Give Friend or Follow a try and let me know what you think? I will also would like to know if there are other services that you know of that is as cool as this one.
