You don’t have to be a geek to know what a friend is. But in the virtual world, and especially the world of social networking sites, the word takes on a slightly different meaning. It’s as well to know this, to save misunderstandings. On Facebook, the relationship you have with your friends is not the same as with your friends in real life. The link between you is altogether weaker. In other words, most of the time, your friends on Facebook are not friends IRL (in real life), but more like contacts: good contacts, sometimes, or they might be people you hardly know.
