I agree. I've heard people say, "I don't understand why you use Reddit. I visited the front page and it is total garbage." But I've never heard anyone say the same thing about YouTube, even though its front page is just as bad.
Something also to consider is that provided I’m logged in, YouTube’s front page gives me pretty great recommendations based on what I’ve previously watched.
On Reddit, however, there’s a huge amount of great content I’m unlikely to stumble upon unless I’m seeking. This makes behavior based recommendations difficult. I think a combination of curated views (software eng front, political junkie, counter culture, etc) and machine based recommendation like YouTube could do great things for reddit.
