These are the worst kinds of threads. For example: http://forums.macrumors.com/showthread.php?t=863263 And not to pick on them, because I don't care who it is. Perhaps there needs to be a single aggregate thread in each forum or area for youtube links, but having a thread started that is essentially just a link to a youtube video is a big time waster. If it is part of an actual discussion on a topic okay, but if it is "haha just laugh at this video." how is that serving any conversation. So I think aggregate Youtube link threads would be okay, so people who feel compelled to share their links with others could do it, without having extra clutter on forums with threads that have no substance but a link to youtube.
