Hi Noah's Dad!,
I've been following your blog!
Whilst I'm not 100% sure how to output Facebook comments to your pages. I have just installed Facebook commenting on my website (a very easy job of just pasting in some HTML with a dash of php to retrieve the current URL). Its great as people instantly recognise the comments box and seem happy, almost eager to leave a comment. Plus its not restricted to just facebook users, people can join in the fun with hotmail, yahoo, or AOL user IDs. Plus I believe more ways of authenticating are being added.
There is a plug in for word press (of course, cos theres a plug in for everything) http://wordpress.org/extend/plugins/facebook-comments-for-wordpress/
Trouble is that the comments are out put into a iframe, thus Google doesn't pay any attention to them (incas eyour doing this for SEO benefit, which I assume you are). But there is a work around to out put the comments outside of the facebook iframe, though I'm still debating whether to do it as it involves hiding the content (otherwise it would appear twice, once in the Iframe and once outside of the iframe, making for a bad user experience), but since Google may frown upon hiding content on my page, I've stayed away for the time being. (unless someone else has a better idea).
Hope that helps in some way.
Regards
Aran
