Now when you comment on a post, the commenting system is all through Facebook. This will help cut back on the amount of spam comments that come through.
If you go to http://insaneindustry.com to see the blog. Go to any of those posts and the comments are now handled by Facebook rather than WordPress. Facebook will help cut back on the number of spam comments that come through. It will also help the exposure of the site. When you make a comment on a blog post, you have the option for it to show up on your Facebook page. If anyone replies to that on Facebook, the reply will show up threaded here. So you can have conversations about a post without being on the site. Also, since it can post to your Facebook page (optional) more people will see the links to the site and hopefully drive traffic here.
