Not really keen on using facebook's plugin. 8 months ago, this plugin locked out 100 websites i host, and upon loggin attempts, redirected users to a subdomain on facebook with the user names and passwords in the URL. I had to repair my SQL, and remove the plugin via FTP, AND CHANGE EVERY PASSWORD.
Why isn't there a simple quick clean solution for facebook comments, and why does facebook have NO @mentions for their API's? Kinda defeats the purpose of claiming to be the central source for dynamic networking. Well, of-course, you could always use disqus (the most widely used commenting system ever used). The Disqus comment plugin loads quicker than one facebook like button if it's not cached. Sorry, not really happy at all with facebook and their lack of cooperation with entrepreneurs. Are they the "groupon" of social networks.
