- turn off Youtube history, there will be no more suggestions based on your recent viewing activity to keep you engaged. Also, searching for a sink review will not result in Youtube suggesting sink-related videos for the rest of eternity.
- install browser extensions: Clickbait Remover for Youtube (sanitizes video previews to remove clickbaity look from them) and DF Youtube (allows you to disable comments, related and other sections on the page, leaving only the video itself to focus on).
Now you should be able to deal with this addiction in no time.
They seem to recommend just the right thing to “okay lets watch this one last video” wasting hours of my day.
Though, I did have to manually ignore a bunch of clips-from-tv -shows type channels.
My main (practically only) use for it is to watch amateur-produced special interest shows that are done on a regular basis. Usually it seems to involve automotive bodywork or subsurface mining with the occasional computer show.
The channels that move to having sponsors or getting a lot of free stuff are for the high jump (although it's absolutely a riot to watch Heather Heying shill for some sofa company, hating life all the while). I think the best ones are done by pure hobbyists.
Otherwise my current plan is to build a library of worthwhile videos via youtube-dl and DVD transfers. My guess is that the ad environment and much heavier copyright policing on youtube will make much of it unwatchable over time.
