This doesn't address your (valid) systemic concerns, but on efficiency the way I like to use links like this is by adding them to a queue for later, then, if I have an opportunity to play them while doing the dishes or commuting or just feeling like watching a television I play them back, usually at higher speed of playback than 1.0. If I'm just sitting on the couch actively watching I'll read ahead in the transcript and skip ahead if I feel like it.
