what you have said there is true, however how many people ever come onto forums posting how good things have been? very few…but that is the whole reason why, happy customers have no need to come on and say this, that is why any forum you look at, will nearly always be full of people who need help and have had problems. I myself use a number of different forums and this point has been menioned on nearly all of them.
happy = no post
unhappy = lots of posts
its the same for me, I bought a car, got conned big time and there are a million posts from me complaining about that fact, however now my car is ok, i hardly ever post as I dont feel the need to.
