Hey, great post and it really helped me get the facebook comments working on my blog. I wanted to get some SEO out of it but the iframe issues (search engines won’t crawl iframes) made this impossible and, of course, the only way I could find to pull the text of the comments was through php scripts (which blogger doesn’t support). Soooo, i wrote a php script and threw it on my server and then called it as an object on my blogger template and viola! – it worked.
In kind, I thought I’d share it with you and maybe add a little value to your already great post. Just paste this code in your blogger template above or below the commenting code and it should be good to go. If you want to view the results temporarily change the opening div tag to just <div> and refresh the page(s) to see how Facebook feeds the text. Hope this helps some of you!
One more note, the php script grabs the referring URL(of wherever you’ve put the html script) so it should work for any and all posts/pages dynamically (including canonical URLs) – I thought that was a nice touch 😉

A final note, I AM NOT a programmer so this isn’t the prettiest thing in the world, but it works great…
