So…what is a Facebook Fan Page called nowadays? A “Like” Page?
The ever-elusive Facebook Fan Page. 
Regardless of what you think about yours, you can’t deny its power: the ‘Suggest to Friends’ link provides an unbelievable opportunity to spread your brand (especially if you persuade your contacts to do the same), the wall allows for a rich content experience unmatched by the likes of MySpace or Twitter, the lack of “friend cap” (see: Facebook personal profiles), etc.
Recently, as if musicians needed more technological changes to deal with, the marriage between Facebook Brand Pages and Fans has extinguished. Users now only have the opportunity to “Like” a page. Please don’t confuse this with the Facebook’s traditional “like” function for pictures, comments, etc. I would have “liked” to see Facebook think about what they were doing semantically before giving two separate experiences on their website the same name, but nevertheless.
Many people are complaining about the new Facebook Page changes, mainly because they don’t understand them. Musicians, I believe that it is better for people to “Like” your page rather than “Become a Fan.”
To be a ‘fan’ of something is a big commitment; to just ‘like’ something is much more casual. In the real world, I personally like a multitude of things, but rarely consider myself a fanatic of a particular sports team or band. Over time, people will be much more likely to engage in this “Like” behavior, strictly based on language alone.
Many artists have been complaining recently about the number of contacts on their pages dwindling. I’ve been getting emails from artists asking me, “Is there some type of Facebook virus? All of the fans on my page are disappearing.”
