As the volume of videos on my Learning with Dr Eugene O'Loughlin I have re-arranged the Playlists to better reflect the different types of videos on the channel. My Playlist selection is now as follows:
Despite this, most of the channel's video views are not through either the channel page or though the previous playlists. Only 0.6% (23,347) and 0.1% (2,187) of 3,800,742 views are via the channel and playlists respectively. So I don't expect the above change to do anything very much to improve viewing numbers, but it will help me to be a bit more organized.
