Content discovery sucks nowadays. The search results bring up mostly bigger channels instead of relevant ones. Recommendations are based on view history and likes, which means you get more of the same instead of someting new. I constantly get videos I've seen already in my recommendations, these stay there for weeks until I click on them.

The major feature I used for discovery is long gone - it was the ability to add video responses, which allowed me to not only find small, niche channels with great stuff but also built a sense of community. I don't get why did they remove this,but ever since they did the site just never felt the same.
