What is a Facebook Page?
Sometimes referred to as a "Fan Page," a Facebook page is a single page
where you can share & talk about any particular subject you want: a
celebrity, a blog you find interesting, whatever your heart desires.
Think of it as a one-page meeting place, with information, links, a
message forum box, RSS and anything else you want.
Want to promote your blog? Then Facebook is one of the best choices when it comes about Social Networking Sites.
