I'm not sure I fully agree, I've found some useful things, but I like long form content that expands beyond what's on Reddit comments and occasionally you hear interesting stories.

The problem I have is, the content I usually see is essentially the regurigation of youtube videos stealing from imdb's trivia section: "Top 10 things you didn't know about $film!"

Quora does the same thing for clicks in a way, and it ends up being misleading.
