YouTube and Normalboots

Jon is the co-creator of the now-defunct NormalBoots website, alongside PeanutButterGamer. Normalboots was shut down as YouTube's partner program became a much better way to earn money than ad revenue on Normalboots. Jon has appeared in videos of a fellow NormalBoots member Continue?.
