I have my Facebook profile set to private yet if I type "Rachael Knox Facebook Newcastle" in Google images a photo of me and my boyfriend from my Facebook page pops up which is quite scary seen as it's suposed to be private!
I think with Facebook just make sure you dont put anything too personal on there and dont click on random links because alot of them lead to viruses.
You will probably get a lot of strangers trying to add you like everyone else does but dont accept them and I would suggest with people you know but dont know REALLY well you should limit how much of your profile they can see through the security settings.
Also with social networking sites people get into the habit of putting there every move on there status lol! e.g. "is going shopping today" or "1 week till my vacation!" make sure you DONT do this you dont want people knowing when you are not home as I know people who have had there homes broken into because of this.
Other then that good luck and I hope you enjoy Facebook
