This is a silly gripe about posters who go on long running posts and post" no more posting on this, let's just let it die" ! Then of course that knocks the post up to the top with a "new" beside it, and then it just keeps going!
If you don't want a post to continue, don't contribute to it in any way, that is how posts die!!!
I must admit to checking in on any post with a "new " beside it, if there isn't then I don't !
