Yesterday I tried to figure out how to post my blog posts on my Facebook profile. First I tried different application but all they could do was adding a box on your profile. After searching for on google for a couple minutes I found one video on youtube that lead me the way: Import Blog/RSS in Facebook profile.
You can do it even easier as in the video. When you are on your profile in Facebook, you just have to click on Import (as shown in the picture) and you can import not only a RSS feed from your blog, but also integrate lots of different websites like Youtube, Google Reader and most important for me: Picasa.
