Sometimes, when pasting links onto a facebook wall the site name under the og:title is a link, and sometimes it’s gray text. There is a similar unanswered question speaking to the same issue: Facebook share 'clickable' url-link issue

Does anyone know what causes this to be disabled?
If the page being shared includes WWW, it’s linked. If not, it isn’t linked. Not sure why but that’s what I’ve seen.
