I have all my Open Graph data set exactly as it is defined in Facebook's documentation, yet for some reason, every now and then when I click 'Like', it'll post to my profile as "...likes .http://mywebsite.com/mypage on .http://mywebsite.com" (inserted periods to prevent hyperlinks). Sometimes it'll get the name right but still display the domain for the site name, sometimes it'll just display the title, and only part of the time does it actually display both the page name and the site name correctly! And then, just to make things even more confusing, posts that used to be correct will switch to displaying URLs instead! But... if you hover over the page's url, you see the actual page title in the tooltip. What's going on here????
