Facebook is the new communication method on the net. If your not yet on the facebook.com site, it would be a good idea to subscribe because we count users by millions on the site.
Very popular with young people, even more then MSN messenger, Facebook let you exchange photos, videos, games and messages with friends or stangers everywhere in the world.
Every Facebook users create is own profile and can choose to show it to the world or simply to his friends. Community of Facebook are spreading everywhere in the world, just like Canada, Quebec, England or China. Every users can create groups and community where everybody can join.
This new way to use internet permits interesting exchange between people, but also open a door on your private life. All your public messages or conversations can be read by your friends (or stangers if you don't have a private profile!)
But you have to be careful about invitations that you receive via Facebook. Buisness are getting more and more on that machine that joins together millions of people. That's why they want by any means to subscribe to Facebook (like Coca-Cola). However, more companies are trying to invite you to events that look like nothing, but are in the end promotions to do some placing of products. Be careful before adding a company in your friend list, because this one can maybe use your name to influence people you know.
You can see lately that Facebook upgraded the control of it's private protection. You can now choose how munch of you you want to show to the world!
