Customer feedback is very important. Whether they have an idea, or somethings wrong its always a good thing to know what your readers think and how they feel. Below i have listed the most popular feedback services on the web. All of them offer great cons and features. They are different, but have the same thought in mind which is feedback. Look around and find the one that covers your needs. Some are priced and not free. Although that is a downside, you have to keep in mind you get what your paying for. Please comment if you know any others, thanks!
