I don't like the idea of making my friends become fans, and I'm not sure some of my friends have necessarily gained my respect enough to consider myself their fans. I've seen this complaint on the FB news feeds a lot!
With Facebook, suddenly any artist can have a "fan club", converting all their "friends" to "fans" and shifting how both fan and celebrity view their relationships with each other.
Well, now FB has changed the "become a fan" button to a "like" button as a way of garnering new members.
A bit deceptive, perhaps. Just because I "like" someone, doesn't mean I want to hear absolutely everything about them.
Still, the "like" button does take things down to a more rudimentary, broader level. your friends just "like" you or at least something about what you do.
For you - the artist or business owner - your job is think of how to keep people liking you. Consider what that takes when you are determining what to communicate to your audience.
