We have discussed this in the past, and came to the conclusion that sometimes there are valid reasons for reviving an old post, so closing all of them would not be a good thing.
But if you try to post into an old thread (I think more than 6 or 12 months old), there is a reminder that you need to click through in order to post a reply. Our hope was that people will read it before clicking OK
Let's take this discussion to the JavaRanch forum.
