Well, when I see that ! ... I certainly get on it right away and remove such broken links. I do not get many to actually get tired of the broken links. However, I am disappointed when it happens to be a specific video that is just perfect for a particular hub and then I can no longer use it. However, sometimes that is not the case, and one just has to go back and re-enter it. I know when I have linked other hubbers' related hubs to a topic I am writing about and that particular hubber happens to no longer write for HP, then I am glad to know of the broken link so that I may remove it. I try to catch these as soon as the pop in when I get the notification.
