Marc, listen to me. I don't want to be mean but someone's got to get through to you here.
You have been posting videos from youtube non-stop. All of us have access to youtube, we can find and view videos we like by ourselves at any time. We're not going to like all the videos you like. Maybe 50/50. But when we look for videos ourselves, we want to see 100% of the videos we click on. It's not necessary for you to post a new topic for every video you like on youtube.
You can see that people aren't responding much anymore or even clicking on the topic because they aren't getting much out of someone else's favourite videos. Maybe the odd video that you think is really relevant to a topic we are talking about is useful, but most of these aren't relevant here and you've got to think about how worth it is for you to use your time on something no one is appreciating.
