Do you think facebook is a good way to contact people?

The answer to that is 50/50!
In a way you are correct. People can send letters and call there friends and family. However FB is also a great tool to get to know people you recently met, show your friends and family pictures all in one, so you don't have to repetitively send it. You don't pay to go on FB, Whereas with sending letters or phoning you have to pay a small price (stamps, minutes on a phone, etc.)
There is a Privacy risk, you should make sure everything is only visible to friends and family, or friends of friends, so no "weirdos" get in or invade your privacy.
The fact that you mind FB is your personal opinion. I know some who feel the same, but the majority of people I know and met love FB. I find it a good tool to meet new friends and meet more people of a certain community or subculture, etc.
