Are my concerns about Facebook unfounded?

All of my family and friends think it is wierd that I don’t have a face book account. I don’t want one for the following reasons.

1. Whenever something becomes as large as face book, they start to sell your info. After all don’t expect something for nothing.

2. There are some friends, I’ve lost contact with over the years and I would like it to remain so. I really suck at saying, no, I don’t want to be your friend. Moving has always given me a nice way of cutting some ties.

3. Once family gets you on your friends list, may really get into your business and one of the things that was always nice is that I only get to see some of them a few times a year. I know plenty who have dragged into family drama because they keep in touch on face book.
I really rather avoid any drama.

4. I have skype and many can reach me on that and on my cell or home number. Is it really necessary I keep some sort of diary of my life for others to keep in touch. Why don’t they just use skype where we can remain in touch and not have to share everything with the whole planet.

5. Once anything goes on the web its theirs to do with as they wish. Pictures and info. Not really trusting of that.
