The Vlogbrothers' videos have been watched over 20 million times
All Vlogbrothers videos have been watched by more girls than guys, with the exception of the videos that featured giraffe sex as the center screenshot.
The Nerdfighters have posted over 27000 pictures, almost 10000 blog posts and almost 6500 discussions.
Don't know if there are any other stats available...
Doesn't matter, the number's hopelessly outdated. The video about killing a person mentions 11 million, but in the "Internet Sensation Bitch" video, Hank corrects it to 13.9 million views, which is also hopelessly outdated because they're over 20 million already.
