youtube kills productivity, use a good solution (instead)
i would recommend to offer an alternative to youtube at least for workshop/learning videos
youtube disrupts the video every few minutes and kills productivity/focus
my impression is that youtube places advertisements often when in the video an important point is announced / stressed. this really makes the learning content overall bad.
there are alternatives to youtube that offer further advantages, like (probably most well known) vimeo.
another option would be to offer the videos for direct download (also better for train rides, ....).
if there is an important reason for using youtube it is OK to use it also, but a good quality option should come first.
further youtube is blocked in some countries, relying on youtube keeps some potential customers away. the following picture shows the aspect not totally accurate (yt is not blocked in germany as i can confirm - another example for google quality ...)
