Similarly to how you use a newsletter to drive traffic to your blog, you can use the same concept with Facebook.
Summarize or begin an article on Facebook, and then do a "Read More" or "View Full Story" and have it link to your blog (a post or page).
In following this concept, when you use NetworkedBlogs, a popular Facebook application, to have your blog posts feed into your Facebook page (or wall if personal blog), it automatically does this – shows only a snippet of your blog post where the user will need to click on it to read more.
