Found this interesting message when I went onto one of the pages I admin on Facebook this morning:
It seems that Facebook is doing away with dealing with ‘Fans’, substituting for the lighter-weight term ‘Like’. As far as I can tell (thus far), “liking” a page on Facebook is the exact same thing as “Becoming a Fan” was.
Facebook has yet to change their “Become a Fan” button to the new “Like” button on some profiles and also the Fan Badges that you embed on your webpages.
