Like it, but it seems to have some issues.
I submitted a page from my own website, and it advised:
* 10 Warnings. 1 Issue. Improvements Needed
* Incomplete Open Graph tags
* Recommendation: Add og:title, og:description, and og:image for better social sharing
I note that the "10 warnings" are not displayed. It would be nice if they were. And my page has og:title and og:description, so I'm not sure why those in particular are flagged as absent. The og:image is, indeed, absent.
