I run a couple forum sites using vbulletin. Both have highly customized templates. Recently I noticed that Google stopped putting "x posts - x replies" under the page name in SERPs.

So my question is, what is google looking for on the page to get those numbers? Why would they stop displaying them? Does Google no longer think that the page is a 'discussion'?
