shore Facebook is in theory the opposite of basic online rules, you interact whit people, post images and personal info about yourself and if you're not careful and sett security settings it's possible for anyone to read all about you, however facebook is a great way to interact whit friends, family and others, instead of calling all of your friends saying: i got a haircut, you post a simple text on Facebook saying the same, all of your friends can read, comment and like it, you can let friends view your holiday photos whit out having to send all of them a bucket of paper or send a thousand emails, just upload them to Facebook and everybody can see them. Just to add to it Facebook actually do have great safety customization features so if you wanna keep things private it's easy. And yeas, it is a lot of commercial, due to the fact that Facebook get's about
1 000 000 new user every single day, i believe that it's a great market for commercial there and that you get pretty good product placement there, some people are easily affected by commercial's and such people should not use Facebook unless their spending can be controlled. If you have some basic knowledge about being careful on the web, not talking to strangers and such things, Facebook is nothing more than an awesome way to interact and keep in touch whit your friends, family and others.
