Honestly, that's where I get some of the most use out of YouTube, the recommended videos main page. Sometimes I'm annoyed they aren't showing me enough variation based on my subscriptions and past likes. I'm not sure why I'd want this. Sometimes I'm watching a technical presentation/talk by someone and I'll get other talks of theirs on the recommended videos for that video page, which is useful, or followup videos on…
YouTube does great at recommending videos. I love it, personally. But I can totally respect the former position as well.
