I believe that the most people have a Facebook profile where they can maintain contact with family and friends around the globe or only with people in their hometown. However, Facebook is a fantastic platform where you can make your homepage/blog more visible for the whole world. I have many friends around the world and my family live in Brazil so I keep contact with them in that way but Facebook is so much more than this.
Not everyone has a WordPress page and therefor Facebook is perfect in order to get more readers and it can increase the traffic on your blog/page. When I did it I invited everyone of my friends and family to like my Facebook page so that they could get the updates that I do on my blog directly on Facebook by updating my fan page.
If you have a fan page please leave the link to your page so that me and others will have the chance to check it out. I have a fan page and if you want to follow me you can just click on the link below.
Facebook let you keep track of your stats which is a good way of knowing whether your work is successful or not. I use this a lot to know how popular my posts are and what types of posts that brings most interest in people.
