Unfortunately I think Marcus Butler is now one of the most boring youtubers, I used to be such a big fan but now he posts every day I feel like he has ran out of things to do for videos and its not very entertaining anymore. Its a shame because Marcus was great! Also Zoella, of course
The issue I've run into is growing out of a youtuber's type of humor, I've never personally found a youtuber boring until I've watched them for so many years. For example, I used to watch swiftkaratechop from 2008 to 2012. Now years later I find his humor boring and his channel is practically dead now. Sumfight or Cody Rapol is another channel I used to watch, then I grew out of that channel as well (he stopped making videos less than a year ago). 3 Canadian youtube channels I used to subscribe to: Andrew Bravener, MattG124, FluffeeTalks.
