Once these pop stars have had their fiftenn minutes of fame they will probably not have the talent to cope with discerning adult audiences who are not so much interested in fads, images and high levels of infatuation as impressionable teenagers.
I also think that a lot of people have difficulty in forming an objective opinion which is at odds with the majority.......they would rather follow the herd instinct even though the herd have no idea why they are following each other and no idea where they are going. They do not want to be at odds with any of the others.
I form my own opinions based on my experience and taste. The herd usually have a different agenda.
