Maybe Google could add a link to the last page of the thread in the results page, next to the 'usual' link to page ... 7, which neither the first, nor the last page and it may contain outdated information that just ranks better.
Moreoever, I certainly hate it when my forum's thread is #1 result but Google says that this particular thread was last updated a month ago, when in reality it a fresh discussion.
I see this happening a lot and may direct users to other site just because Google's date is not updated as often as it should. My forum get 1mil pageviews/month but still, the date is wrong.
