Q:

Why is Facebook not reading OpenGraph Tags in my page? 

I have a page I am developing with OpenGraph tags: http://william-j-bennett-iii-dds.nationaldentalreviews.org/?qRID=252851
The tags are correctly picked up by other Opengraph page crawlers. 
But the Facebook page crawlers are not picking up the same data. 
Is there an error in my Opengraph Tags that I can fix?   Or is there an error with FBs process? 
UPDATE 10/3: Let me clarify, here are the OpenGraph tags as they are parsed by the parser on "opengraph[DOT]in":
og:site_name: Aesthetic Dentistry
og:title: We're so grateful for good reviews from our customers.  Here's another:
og:type: profile
og:url: http://william-j-bennett-iii-dds[DOT]nationaldentalreviews[DOT]org

A:

The problem is that Facebook requires all OpenGraph meta tags parameters, although they're not strictly required by OpenGraph itself.  You strictly need to specific the og:url and the og:title meta tags
