How can so many people be so ignorant to join false Facebook groups?

[Jim]

The basic fact is that no one person can ever feel 100% satisfied with Facebook (or MySpace).
They are designed to suit the majority - not every single user.
I'm sure Facebook are aware of this Groups trend and have decided to ignore it on the basis that young people are like sheep - they will follow anything.
If one popular celebrity praises a new band that nobody has ever heard of, that band will have thousands of fans within weeks because somebody, just one person, whom young people already respect has expressed an opinion.
Aside from that, young people often join a group merely for the feeling of belonging. The phrase "get a life" is overused and misused, but the fact is that many young people are dissatisfied with their lives, and belonging to something, no matter how trivial, makes them somehow feel better about themselves.
