Testing Facebook comments

I've enabled Facebook comments on my blog posts. As a result, if you post a comment, it will show up on this post's page and also on my Facebook page. This will reduce the amount of fake comments because only people with Facebook accounts can post comments.
I realize that this may pose a problem for those who don't have Facebook accounts or who don't wish to use them. Please bear with me during this experiment. I've also seen that, in the past few months, all of the people who've commented directly on the blog posts (on the Roasterboy site) are already Facebook friends.
