Something important to remember about social networks is that although privacy settings are a great tool, you can’t apply a privacy setting to another human being.

When we share information online we don’t really control it anymore because someone else can copy, change and use it for themselves.
For lots of social networks you have to sign up terms and conditions. Because there are usually so many of them, people don't read them as they just want to get on with social networking.
