I watched that interview of Dr. Pat Baccili with Paul. Like I often do I clicked on the Youtube logo, so I watched it in Youtube. There it's possible to give the
video a 'thumbs up' and to comment. I was surprised to see it had only 1 (one!) thumbs up. Of course I gave it a second one, and I wrote my comment.
Maybe many more have watched it here, at Permies ... but then Youtube doesn't count those views. As far as I know more people will see it (because Youtube will show it) if it has more thumbs up (or even thumbs down!) and more comments.
