Social networking sites such as Facebook and Twitter provide a great conduit for keeping in touch with people you may not otherwise be able to keep in touch with.
They can also be very entertaining (FarmVille, anyone?) and keep you hooked for hours on end.
However, while these sites can be a great tool, it’s also important to remember that they are very public and permanent. That’s why it’s important to make sure you know the people you are adding as “Friends.”
When online, it’s difficult to be 100 per cent sure of people’s true identities. If online friends have little or no real-world connection, always use caution. The more real-world connections with an online friend, the more confident you can be in sharing information with that person.
While you can be confident in sharing your vacation photos online with your real-life best friend, you might want to think twice about sending those photos to the friend you met through another friend while chatting online.
