Personally, I don't put Youtube in the social network category because most of its users are passive consumers. I think social networks as systems that explicitly model social connections and whose users have a relatively high ratio of send-actions to receive-actions. That said, Youtube does have many of the same social problems as Facebook (e.g. use as a cheap and effective channel for pushing disinformation, cultivating hyperpartisan filter bubbles, etc.).
