Remember when a lot of people used to think that the blue "e" icon is the internet, and "Microsoft" is "Word"?

Probably now many Facebook users think Facebook is the internet. Good luck!

What I mean is: they don't use Facebook because they think Facebook is so great, they use it because their friends use it (like email - it is just a way to send each other messages). They probably never questioned why they use it. Therefore it would likely be hard to make them switch to something else.
