google absolutely sucks at it, probably because they don't see any value in it given their user base (everyone) and lack of competition.

i.e. my youtube front page just shows the same 100 video links over and over and over.

there isn't even a really good way to discover relevant content in the channels i've already subscribed to. it's pretty lame.

YouTube makes me want to punch my computer.

The related videos are never relevant, letting a child meander through YouTube invariably winds up showing my kids super inappropriate content. The YouTube mobile app sucks horribly (ios) I literally think that YouTube is one of the worst ubiquitous services there is.

This isn't a great solution, because kids are pretty good at getting out and into whatever app they want, but there is a YouTube Kids app. It's more like streaming TV than YouTube.
