So...what about this other case then? And thanks for the post the summed it up very well.
Nothing in principle, but FR not simply meant to not inform but it is a forum, a place for an exchange of ideas and commenting and even debate thereof, and having to watch a video on a debatable issue - esp. one that is over an hour long - before being able to weigh in the merits of it militates against it. The author of such should be able to provide his main points in readable form.
The exceptions are when a vid is posted for entertainment or simply education vs. something quite debatable.
