I subscribe to quite a lot of youtubers for different things, for instance:
-TeamFourStar (DBZ:A)
-Linus Tech Tips (Hardware/general nerdary)
-Unknown Melodeath and Unknown Power Metal (both metal channels that highlight lesser known bands of their specific subgenres)
-Lets Play / Achievement Hunter / Rooster Teeth (...general fun? Been a fan of theirs since pre-YouTube, have followed them along their journey)
-Palmers FC (Sunday League Football, good fun to follow along with and to go back to their old videos and see just how far they've come)
-First We Feast (Hot Ones, amazing show)
-Thogden, Stunt Pegg (Both Bolton Wanderers vloggers, gotta' support my team

)
...and so on. I've got channels I watch for retro gaming content, channels I watch for music content, channels I watch for hockey and football content, channels I watch for gaming content, and so on. A real hodgepodge.
