I only subscribe to a handful of channels, like Arlo (despite his child-friendly appearance, he offers fair opinions and reviews), Spawn Wave (for news and rumors), and Gamexplain (for game discussions and analysis).
56. Though a big majority of them are not active anymore (I just keep them so that I can easily access their old stuff), and some of them are the same people with multiple channels for different purposes. I mainly just watch Smosh and Game Grumps nowadays. I never subscribe to someone unless they've got at least one thing that interests me.
around 90 apparently, though looking at it, there's a decent amount of people who just don't make stuff anymore or only put out a video once in a blue moon
out of the active people, there's a few that I don't really watch, but everyone else I do keep up w/
