Everyone has a voice.
Whether you hear it or not is another thing BUT you can decide who you listen to.
The 1% rule online dictates that 1 in 100 people will place a comment. As a blogger these are the people you tend to listen to. However what about the other 99?
The same goes for negative comments, if you hear 20 good comments and one negative you tend to focus on that one.
Remember to make sure that you are listening to the right people.
