If you are viewing a forum now (like this onehttp://forums.microsoft.com/msdn/ShowForum.aspx?ForumID=53) the "last post" column lists the correct person, but the date seems to be the date the first post was made. The date there should (and was before the update) be the date the most recent post in the thread was made. This was how I was quickly scanning forums by looking for the today/yesterday tags. :-)
