What are valid reasons to stay out of facebook? or not to register there?

[Common Sense]

It seems like almost everyone has a facebook account these days. My family and some friends want me to join, but I simply do not want to do that, even though I know I can set my desired level of privacy.

I want to talk to my friends and family, not comment or "like" them.

I don't want to connect with 472 old friends. I love my circle of friends and do not want to have to "friend" virtual strangers who tag me to do so.

I do not want to waste my time reading everyone's stupid comments.

I have known several occasions where facebook has caused drama due to misunderstandings.

It is impossible for me to take facebook seriously, therefore I do not bother with it.

Social networking in cyberspace is impersonal and lacks my desire for human contact.
