When you run your own business you can end up becoming heavily invested in your business' success and failure. Comments and feedback, both positive and negative, might affect you more than you would like to admit.
Over the last few years the company I founded has grown from operating out of a bedroom (or two) to having a fulltime staff of close to 20.
Over the years we've improved some things, made a total mess of others, delighted some people and really annoyed others. (In many instances the "love" and "hate" is directed at me personally, as I am the most visible person associated with the company).
The harsh reality is that no matter what you do you cannot and will not please everyone all of the time.
Since I'm interested in my industry I track certain keywords on Twitter, so watching people talking about some of our competitors can be very enlightening.
GoDaddy, which is simply massive in terms of its customer base, proves my point.
Just watch how people react to them over a 24 hour period.
You will see both ends of the scale.
They're all talking about the same company during the same time period, so it's really fascinating (to me at least) to watch.
