Rhett and Link!!
I love those two and have a passing interest in but less tolerance for the usual suspects -- Tyler Oakley, Jenna Marbles, etc. I also actually like PewDiePie.
Oh also my daughter + friends' YouTube channel. One of their videos has over 500,000 views!
Also depends on what's captioned, there are some I'd probably like if they were, but they're not.
